My Great Grandfather was Harris Epstein the Great Inventor of a Patented Folding Umbrella, Extension Ladder and more


I am named after my great-grandfather, Harris (Tzvee) Epstein, aka, Epstein the Inventor, who lived in New York City and Spring Valley. I probably inherited my technical curiosity from him.

He was the inventor and patent holder of many practical items, a folding umbrella, an extension ladder, a double sided toothbrush, a vegetable grater and more.

Here are of his patents with their links from Google Patent search: 

FOLDING UMBRELLA Patent number: 1666692 Filing date: Jan 29, 1927 Issue date: Apr 17, 1928

SIGNALING APPARATUS US Pat. 1060898 - H. EPSTEIN. SIGNALING APPARATUS, APPLICATION PILED JAN. 26, 19.11. Patented May 6,1913.

TOOTH BRUSH Patent number: 1111144 Filing date: Oct 4, 1913 Issue date: Sep 22, 1914

Papa Epstein, as he was called by his grandchildren, sure would have liked the age of the personal computer and the Internet, especially the iPad and smart phone.

Was Benoît Mandelbrot Jewish?

Yes, Benoît Mandelbrot was a Jew. The Times obituary says he, "was born on Nov. 20, 1924, to a Lithuanian Jewish family in Warsaw. In 1936 his family fled the Nazis, first to Paris and then to the south of France..."  Wikipedia says that in France, "He was helped by Rabbi David Feuerwerker, the Rabbi of Brive-la-Gaillarde, to continue his studies." Mandelbrot is the Yiddish word for almond bread, the Jewish biscotti.

The Times says, "Dr. Mandelbrot coined the term 'fractal' to refer to a new class of mathematical shapes whose uneven contours could mimic the irregularities found in nature." Mandelbrot's discoveries profoundly influenced mathematics and the sciences and numerous disciplines beyond.

Atlantic: Can You Read on an Amazon Kindle on Shabbat?

I originally posted this 12/23/2010. 
The questions keep recurring so we are bringing this post back. And by the way, I published a lot of books on Kindle since then, 
Now back to the 2010 blog post...

Our Jewish calendars have always told us what time to Kindle for the Sabbath, when to "Kindle the Shabbat Candles."

Nowadays we have another kind of Kindle to know about, the Amazon book reader. And the question arises, can you Kindle on the Sabbath?

We think yes, without any qualifications, that you can Kindle on the Sabbath. The e-ink device does not create actual light. You cannot read it in the dark. And it obviously does not create any durable writing. When you turn it off it goes blank.

In halakhic terms we find no transgression, no prohibition to using the reader. In fact it's a feat of great imagination to extend Sabbath prohibitions to that invention. It involves believing there is a set of electrical apparatus that is prohibited, or defining a broad category of technology-things that all are outside the spirit of Sabbath rest.

Our Amazing Incredible Hanukkah Avatar

Hanukkah has its own avatar. I wrote about how this works in my truly amazing favorite book, "God's Favorite Prayers."

...The concept of avatar has several meanings. First an avatar can be an embodiment or a personification of a substantial idea, for instance, "the embodiment of hope"; "the incarnation of evil"; "the very avatar of cunning." In some respects I describe in this book how the prayers serve as avatars of several diverse personalities. In this sense I can say that the Amidah is an avatar of the priest.

An avatar in the context of religions can have another meaning. In specific it is a manifestation of a Hindu deity, particularly Vishnu, in a human, superhuman or animal form. As an example of how the term is used is, “The Buddha is regarded as an avatar of the god Vishnu.” In this sense of the term, I created my archetypal avatars, such as my “priest,” as representatives of the core values that inhere in the prayers...

... The most recent technological application of the word avatar denotes a computer user's self-representation or alter ego, in the form of a three-dimensional model within a computer game, or as a two-dimensional icon picture on a screen, or as a single-dimensional username within an Internet community.

... On two special occasions, Hanukkah and Purim, we add paragraphs to the Amidah to describe the victories of heroic Jews of the past. I see these hero figures as avatars of the priest.

Are Coronary Stents Kosher?

Yes, coronary stents are kosher. In fact they are a miraculous invention.

What are they? Wikipedia says: "A coronary stent is a tube placed in the coronary arteries that supply the heart, to keep the arteries open in the treatment of coronary heart disease. It is used in a procedure called percutaneous coronary intervention (PCI). Stents reduce chest pain and have been shown to improve survivability in the event of an acute myocardial infarction."

The coronary stent was invented by Julio Palmaz. The stainless steel, insertable mesh stent is expanded once inside the body to hold an artery open and allow blood to flow more freely. Palmaz secured funding for the development of the stent from restaurant owner Phil Romano (Fuddruckers and The Macaroni Grill). Palmaz co-developed the stent with Dr. Richard Schatz, a cardiologist at the time at the Brooke Army Medical Center. We would guess that Schatz is Jewish. They patented their invention in 1985.

The coronary stent is one of the greatest inventions of our time. The stent can be inserted through a small puncture in the groin or wrist and via balloon angioplasty it can open up quickly and with little to no pain a 99% occluded major coronary artery. The procedure takes about an hour and the patient is ambulatory after four hours and can resume many of his favorite activities :-) within one day.

To a person (like me) with CAD this rapid and amazing restoration of a person's quality of life is a true medical miracle of our times.

High Recommendation: Tello Mobile Service - a good idea for existing Sprint Customers


After many many years with Sprint, I have switched to Tello Mobile. They are a discount MVNO for Sprint - a mobile virtual network operator. That means they provide the Sprint network to you for calls and data - at a substantially reduced price. 

Until 11/1/19 you can switch and get your first month of service for $5. I find the $19 monthly plan to be sufficient to my needs. Unlimited text and talk and 4 GB of data.

The sacrifice for this? I gave up an unlimited data plan and free roaming - but I do not think I will miss either of these. I might miss their global roaming - but that was a throttled and limited convenience. Wherever I travel, I use a local sim card.

It's not the savings of money that drove me to switch. I grew tired of Sprint's terrible service. They did not deliver a promised offer after I added a new line. And they started signing me up for services that I did not want. And it took them weeks to unlock a phone for me for use with any sim card.  I was wasting a lot of time trying to get Sprint to do or fix things on my plan.


And it is easy to switch.

You can port your Sprint number to Tello and use your existing Sprint phone and sim card. All you do is supply Tello online with your phone's MEID and SIM numbers - which you copy from your relevant phone setup screens - and give Tello your account number at Sprint and PIN number.

It takes a few hours for Tello-porting to occur, if you start the process on a weekday morning.  When ready, you will know because your calling capability will stop on your phone. Your phone will need to be rebooted by calling a simple code the Tello support team will give you. After a few minutes and a few restarts, you will be a new Tello customer.

Are Crocs shoes permitted on Yom Kippur?

I recall posting this in 2009 - and now I have Croc-like shoes that I plan to wear in a few hours to shul for Kol Nidre on Yom Kippur. My shoes are quite comfortable.

It's my impression that the brouhaha of 2009 over this issue has faded away and now it is permitted to wear these shoes on Yom Kipur.

Here is my post from 2009.............. Enjoy! ... Gmar Hatimah Tovah to all!

The Internet is buzzing with the late breaking news that a prominent Orthodox rabbi has banned croc-wearing on Yom Kippur because the shoes made from lightweight, antimicrobial foam are too comfortable, even though they contain no leather.

Crocs have sold 100 million pairs in seven years. Of late, the company that makes them is rumored to be in bad financial straights.

We have never owned or worn crocs. We checked with a relative of ours, who prefers to remain anonymous, who informs us that he has worn crocs on several occasions and that they gave him blisters each time. Apparently, the rabbi has been misinformed as to the comfort of the crocs brand of shoes.

We do not issue on this blog religious rulings for others to follow. But we can tell you that it is our informed opinion that if we were to wear crocs on Yom Kippur we could rest assured that we had not violated any prohibition in the Torah.

Rav Elyashiv: Crocs Should Not Be Worn On Yom Kippur

rav-elyashiv1crocsThe posek hador, Rav Yosef Shalom Elyashiv, has ruled that Crocs should not be worn on Yom Kippur. Matzav.com had actually reported this ruling of Rav Elyashiv before Tisha B’Av (see here), but now the p’sak has been reported in Bakehillah and various news outlets. The p’sak is based on the fact that the issur to wear leather shoes on Yom Kippur is because they are considered the most comfortable footwear and are therefore included as one of the five prohibitions, or inuyim, of Yom Kippur. Thus, Crocs which are especially comfortable, ruled Rav Elyashiv, should similarly not be worn.

Israeli Chief Rabbi Yonah Metzger and others had previous ruled that Crocs are allowed on Yom Kippur, even though they are comfortable, because they are not made of leather. They say that in the past, as mentioned, the prohibition on wearing leather shoes was because they were considered the most comfortable, and therefore, they claim that just because nowadays rubber shoes are no less comfortable, they, and similar sport shoes, are permitted.

The posek hador has disagreed, however, and has ruled that comfort must be considered, and therefore, Crocs, which are worn for their extreme comfort, should preferably not be worn on Yom Kippur.

See Matzav.com’s earlier report here which contains the views of Rav Moshe Shternbuch and others.

Is the Hullin Scroll the Oldest Talmud Manuscript Ever Found?

What is the oldest known Talmud scroll?
Scroll of tractate Hullin, Babylonian Talmud (CUL T–S MISC. 26.53.17), acknowledgment to Dr. S.C. Reif, Director of the Taylor-Schechter Genizah Research Unit at the Cambridge University Library, and the Syndics of the Library.

I was delighted in December, 2009 to hear Professor Shamma Friedman speak at a Talmud department seminar at JTS. He spoke about a controversial scholarly issue: whether Maimonides intended his Mishneh Torah to replace the Talmud.

This event reminded me of a Talmudic fact that Professor Friedman brought to light several years ago, i.e., that the Talmud was at an early time circulated in scroll form. He discussed this in his paper,  “An Ancient Scroll Fragment (Bavli Hullin 101a-105a) and the Rediscovery of the Babylonian Branch of Tannaitic Hebrew,” JQR 86:1 (1995), pp. 9–50.

My Dell Computer was really good


On 1/3/2008 I bought a Dell XPS 420 quad core PC. I believe it came with Windows Vista installed.

Last week, after eight years and nine months, it started crashing to the dreaded blue screens of death. I worked for many hours to rescue the machine from whatever it was that caused the crashes: corrupted device drivers or malware or hardware malfunction. I reverted updates, scrubbed registries, removed many old programs, ran defragmenters and virus defender software.

OK. I got the unit working now smooth and fast, It has not crashed for a day. I maybe even fixed it. But meanwhile I ordered a new Dell XPS 8900 i7 computer. I got a good deal direct from Dell with discounts and a good service plan included.

Nearly nine years is enough. All computers die eventually. Even the good ones.

My Dear Rabbi Zahavy Talmudic Advice Column for August 2016: Are there any Magical Jewish Cures and Curses?

Your Talmudic Advice Column

Dear Rabbi Zahavy,

My friend has started to scare me. She tells me often about her beliefs in the magical powers of religion and religious people. She claims to have witnessed faith healings right in front of her eyes. I think she’s gone off the deep end. Guide me please in what to do.

Scared in Secaucus

Dear Scared,

There are charismatic religious leaders in many religions who say that they can cure people of illnesses. In Judaism we say that we do not believe in, or practice, magical faith healing. The Torah condemns sorcerers, soothsayers, and witchcraft as abominations. But also note that the Torah tells us about Moses’ magical staff, capable of outperforming Pharaoh’s magicians. And some say the magical phrase Abracadabra comes from Aramaic words ארבדכ‭ ‬ארבא‭‬ that mean, “As I speak it, so it shall come to pass.”

Is Amazon Echo Jewish?

Name Your Link



Is Amazon Echo Jewish?
I ordered an Echo when it came out at the end of 2014 - it's a voice activated Internet invention from Amazon. My son Barak observed about it that it looks a bit like a Shabbat lamp (which I do not have) and wanted to know if it can be used on Shabbat. And that made me think.

If Echo is Jewish, then you can't "suggest" to it that it do any work for you on Shabbat. You can't say, "Play me a niggun" or ask "What time is minhah?" or clarify "When did I last eat meat" or, on Pesach, "How many matzas do I need to eat for a kazayis?" and I could go on.

But if Echo is not Jewish, then you potentially could ask all these requests of it on Shabbat or Yom Tov..and more.

Q: "Alexa are you Jewish?"
A: "People all have their own views on religion."
Q: "Alexa are you Jewish?"
A: "I'm best at answering questions about things like history and music."

Alexa is evasive.

Q: "Alexa, Play me the Israeli national anthem"
A: "Here's a sample... by Michael Silverman."

Amazon ran some quirky ads during Super Bowl 50 for the Echo.

Is Alec Baldwin Jewish? Nope.

Alexa did not know that. Hmm...

My Dear Rabbi Zahavy column in the Jewish Standard for February answers questions about hand shaking hygiene and avoiding speeding tickets.

My Dear Rabbi Zahavy column in the Jewish Standard for February answers questions about hand shaking hygiene and avoiding speeding tickets.

Dear Rabbi Zahavy,

I have had serious health problems and several medical procedures that weakened me and my immune system. Thank God, I have recovered now, and I attend my local synagogue. My problem is that especially on Shabbat, some of my friends and neighbors offer me a handshake with their greetings after services.

My doctors have cautioned me about engaging in physical contact in public that could expose me to germs and diseases. So I have told my close friends that I won’t shake their hands. They understand because they know my situation. I offer some of my buddies fist bumps instead of handshakes.

Other people in shul do not know why I won’t shake hands with them. That makes me worried that they will think I am socially cold or odd.

First, am I wrong to be hyper-cautious about handshakes? Second, what should I do to explain my preference not to shake hands?

Fist-bumping in Fair Lawn


Dear Fist-bumping,

Our hands most certainly do have and transmit germs. What should we do about that?

Thank You New York Times for introducing me to virtual reality for free today

The Times delivered a cardboard virtual reality viewer to my door today with the weekend paper.

I had no clue what it was or how it worked. I followed the steps and folded the viewer, downloaded the app, put my android phone in the viewer, and played the videos.

It was incredible, magical and mysterious.

Mashable explains:
After an October announcement of a partnership with Google to produce virtual reality (VR) films, The New York Times has launched its new VR app, appropriately titled NYT VR, on Thursday. The app debuted with two feature films, one titled The Displaced tells the story of three children swept up in the world's refugee crisis, and the other shows making of a recentNew York Times Magazine cover.
If you did not get one from the Times, buy yourself a cardboard viewer and try it out.

VR is going to be big.

Swipe Your Mobile Phone for a Jewish Date: My Jewish Standard Dear Rabbi Column for August 2015

Dear Rabbi,

My twenty-something daughter told me that she went on a date with a boy she met via a smart phone app called JSwipe. I gather that apps like that are meant to help people find casual hook-ups, and are not intended to lead to a serious relationship. Am I justified to be concerned?

Worried parent in Wyckoff


Dear Worried,

Although many of us have smart phones by now, most of us do not know how an app like JSwipe works. When I got your question, I didn’t. So I loaded the app onto my phone to see how it works. From what I gather reading about the app, it is a knockoff of the much more popular app Tinder. The premise of JSwipe is that it targets a subset of the population — Jewish people.

If you have a Facebook account, you can log in to the app with your ID and password and it pulls in your photos and other information from that site. You answer a few basic questions about your Jewish preferences (e.g., kosher or not, Orthodox, Conservative, Reform or a few others). You can be swiping actively through pictures of potential matches with the app in a matter of minutes.

There is no learning curve. You look at a picture of a possible date and swipe left to reject it or right to accept it. If you swipe right and the other person does as well, then you have made a match. You then can chat with your match in the app and possibly make a date.

Several shortcomings of this technology jumped right out at me. When I tried it out, the app did not actually screen who I was. I downloaded it, signed in, set some values, and was ready to swipe. That should worry both young users and their parents. If the new user wants to meet a Jewish date, you should know that the other JSwipe user might not be Jewish even if they say they are. And yes, Jewish or not, there is no way to know if they are stable or reputable people.

Once you get the app on your phone your activity in it is limited mainly to looking at pictures — many of which are the grainy snapshots that people use for their Facebook accounts. A small percentage of users put in additional descriptions of themselves and their interests.

A user can set some preferences — but not many. You can tell JSwipe the age range you want to see and the geographic proximity to potential matches and set a few Jewish preferences.

I certainly hope that people who match through the app and agree to a date will meet in a safe public place, to get a chance to validate somewhat that their match is a suitable person.

Does this system help people find proper matches? I’m no specialist in the sociology of Jewish dating. But I seriously doubt that this type of superficial app produces many fulfilling relationships or even enjoyable dates. To use totally non-analytical terms, at first blush, to me the system seemed simplistic, rude, and creepy.

Should you be worried if you find out that your child uses the app? A little. Most kids have common sense to be cautious about whom they meet and date. So you need not be that worried. But the superficiality of the choice process and lack of vetting of the population using the app are big drawbacks.

Well okay then. Is there anything you can do to help your kids find suitable dates? Parents I spoke to agree that trying to set up your child with a shidduch is not at all welcomed in the more liberal segments of our Jewish community. Apart from the ultra-Orthodox, who deem arranged marriages desirable, it’s common that children will not want your meddling at all into their social lives. Young people spend a great deal of effort to establish their own identities and their independence.

What I recommend, then, is that you help enable your children to find and join communities of like-minded peers, where they will have a better chance of meeting a suitable date or mate in person. Synagogues, community centers, artistic and cultural groups, charity activities, sports activities, and the like are valid starting points.

Try to be patient and let real human processes of meeting and making dates and establishing relationships take their course.

Bottom line, as you can tell, I’m not impressed with a dating methodology based on swiping through tiny pictures on a phone.

Talmud Tractate Hullin, translated by Tzvee Zahavy (=me)

Kindle Babylonian Talmud Hullin

To know what food is kosher, that is, fit to eat according to rabbinic Judaism, you must study the principles set forth in this volume, the Babylonian Talmud Tractate Hullin. This translation, adheres closely to the text so that the reader has a sense of the structure and balance of the original. Yet at the same time it conveys the flow of the legal arguments and debates, the dramatic unfolding of events in stories, and the sensitivities to words and language in the exegetical texts. Its aim is to facilitate a smooth conversation between readers and the text so that, without consulting the original Hebrew and Aramaic version, they can appreciate the substantive meaning and recognize some major aspects of the style of the Talmudic text.

My Jewish Standard Dear Rabbi Column for May 2015: Love of God, Lights on Shabbat and Appreciating Rav Lichtenstein

Dear Rabbi
Your Talmudic Advice Column

Dear Rabbi,

I’ve recited the Shema all my life, since I was a child, in synagogue and at home. I know it is made up of biblical passages and that it is at the core of our prayers. Recently, though, I started to wonder about the verse: “And you should love the Lord your God with all your heart, with all your soul, with all your might.” The two terms “love” and “God” are difficult for me to understand. I find it remarkable that the Torah instructs or commands us to have an emotion for a religious idea, to love God. Can you help me understand this?

Perplexed in Paramus


Dear Perplexed,

Love is perhaps the most complex of all human emotions. And God is perhaps the most awesome of religious concepts. Each of those is a great mystery to all beings. To love God. How can the Torah command us to engage in such an enigmatic action? You seem perhaps to feel that for you loving God may be an unreachable ideal.

What makes love so complex? For starters, there are many kinds of love. There’s at least romantic love, filial love, parental love, platonic love, unrequited love, undying love, and more. And on the concept of God, there is no end to what theology has to say.

I’ve studied much theology, but let me be honest, I’m no expert in love. Just because I am in love with someone special, because I know the intense fulfillment and the happiness of redemptive love, because I have read books and poetry and studies in psychology and science that explore love, all of that put together still does not make me an expert.

So I hesitate to give advice on this inexplicable subject. I’ll just say that I have noticed a few things about love that may help you find an answer to your question.

I have found that it is true that the object of our romantic love may be a real person, a woman whom we find beautiful and charming and energetic, or a man whom we find handsome and funny and reliable. And we may declare that we direct our love to that other actual person.

But I have concluded that is not exactly the case. I discovered over the years that actually I direct my wonderful inner emotion called love to an ideal image of my beloved that I created interior to my being. My assumption and hope is that the inner persona that I shaped closely represents the real person out there. I hope that I have not put my lover on too high a pedestal or imagined that she is more wonderful than she can be in “real life”.

I feel strongly that I love the real object of my affection through that imagined figure that I crafted in my mind.

And so with this premise, let me come back to your inquiry about loving God. We ought not expect to love a tangible deity directly. When we love God, that love is filtered through our ideas, notions that come to us through our traditions.

When we read in the verse of the Shema, “And you shall love…” it instructs us to direct our fundamental human emotions toward the ideas of a deity that we have formulated. In the Shema, the ideas of God describe a personality who cares for us individually, who keeps track of every action that we perform, who rewards and punishes us. Elsewhere in Tanach we learn about God’s heroic acts on behalf of our ancestors, his reliable promises to protect and redeem us as a people, his handsome mystical majesty, and much more.

How remarkable. Twice daily we are reminded in our prayers to direct our emotion of love toward an abstract entity that we will never see in real time. And we do that by pointing our love toward our inner ideal pictures of an awesome and loving God.

In addition to that direct action itself, there’s a wonderful added benefit to practicing the love of God. I have thought from time to time how being actively mindful every day of loving my inner image of God helps me keep strong my ability to love the images I have fashioned of the other significant entities in my life. Through the mechanisms of all of my inner representations, I seek to connect my real and vivid emotions to those special real people whom I dearly love.

Dear Rabbi,

I read about a new invention: a rabbi-approved light switch that allows Orthodox Jews to turn lights on and off on Shabbat. The convenience of having such a switch on Shabbat could be a significant gain for Orthodox Jews. At first I thought it was a great idea, and I understood that rabbis approved it. Then I heard that some rabbis oppose the innovation. I don’t understand why anyone would oppose it. What’s your ruling on this subject?

Turned on in Teaneck


Dear Turned on,

Your question is grounded in the common sense of our Western culture, which values convenience. You assume a more expedient option for living will be adopted quickly, and you ask me to give you a ruling that accommodates that assumption.

I’m not going to do that. I’ve said here in the past that I don’t aim to render decisions on Jewish law in this column. For that you will have to seek out a halachic columnist — an engineer of the Jewish tradition — who will provide you with a decision of law. Here I’ll offer you talmudic insights — some of the science on which our practices are based — and I’ll leave the application of that to others.

The Talmud offers many principles for defining work on Shabbat. Most of them are technical. Some are ethical. The Shabbat switch inventors claim to have created a device that avoids all the technical taboos and therefore allows the use of electricity on Shabbat. The inventors claim that by using their switch, a Jew will not perform forbidden labor on Shabbat.

So what then makes rabbis object to this easing of the taboos? Apparently some rabbis don’t accept the engineering claims. They believe that Shabbat work restrictions are violated when using the switch. Other authorities don’t find fault with the engineering of the switch. They object to changing the “sacred character” of the Shabbat and to easing the quasi-wilderness experience that the Shabbat rules help create.

Many people of all faiths enjoy recreation, when they can voluntarily go out camping and forgo the conveniences of modern life. Rabbis believe that a similar diminution of modernity defines a special nature of the holy day of rest. It harkens back and binds us to the time of yore, when the Israelites and ancient Jews had no electricity or other appurtenances and conveniences of innovation.

I like to go camping and I do value convenience. And I’m sorry but I won’t decide for you what to do in this case. Ask a rabbi who does the applied engineering of Jewish laws what they prefer that you do. And then I advise you to act according to your ethical imperatives.

Dear Rabbi,

This is not actually an advice question. I was wondering who you think was the greatest rabbi of our times?

Rating our Rabbis in Rockleigh


Dear Rating,

I’m glad you asked this. There are no objective criteria to determine who is the greatest, no elections, contests, playoffs, Super Bowls, or World Series of rabbis. It’s a highly subjective question and one that is based mostly on opinion.

I have several personal favorites among those rabbis who lived in recent years. I’ll tell you about one rabbi who just passed away, someone who made a great difference in my life.

I had the privilege of studying in Rav Aharon Lichtenstein’s Talmud shiur (class) at Yeshiva College for two years, beginning when I was 16 years old.

He was one of the finest teachers that I studied with in college — a genius as an educator and a sincere and compassionate human being. He is the person whom I chose to personify the quintessential scribe personality of prayer in my book “God’s Favorite Prayers.”

Rav Aharon was a special teacher who imbued me with indelible lessons that I have taken with me throughout my life.

Rav Aharon taught me that you could be both a humanist and a talmudic scholar, a lamdan. He clearly loved English literature, which he had studied at Harvard. He often and freely quoted poets John Milton and Edmund Spenser. He happily contrasted the ideas of the enlightenment with those of the Torah. But all the time it was clear to me that literature was his avocation and that learning Torah was his true vocation.

Rav Aharon also taught me that you could critically study and deeply love the lifestyle instructions — called the hashkafah — of the Torah. Each week, we read and discussed a chapter in Rabbi Elimelech Bar Shaul’s inspirational Hebrew treatise, Mitzvah Valev (Tel Aviv, 1956), which means the commandments and the heart. Through that work, Rav Aharon taught us that the cognitive understanding of a commandment had to be joined to the emotional commitment of one’s heart. His lessons had a profoundly powerful and positive impact on my faith.

Rav Aharon taught me that you could be a vitally creative pedagogue even in the most traditional subjects of learning. The college administration told him that he had to give us exams in Talmud, the main subject that he taught us. He used that as an opportunity to teach us more. He gave us thought-questions. Based on something we learned previously, he would ask us to resolve a new scenario. Or he would give us text-questions. He would have us examine a brand new text, related to some passage we had learned before, and then he asked us to parse it and to comment on it. We had to decide what commentary he had plucked the text from, tell him what the text meant, and then explain why we came to our conclusions. That was hard.

That is how Rav Aharon taught me that an exam could do more than ask a student to regurgitate what he had learned. The rabbi tested my knowledge and my thinking powers at the same time, and he was the only teacher I ever had who truly knew details of my personal styles of learning and of my own intellectual strengths and weaknesses. I happily confess that I used elements of Rav Aharon’s methodology of thought-questions and text-questions in many of the Talmud and Jewish studies courses that I taught over the years at the University of Minnesota, the Jewish Theological Seminary, and elsewhere.

After I went on to become a professor, I would take extended leaves to work on my research in Jerusalem. My family owns a Katamon-neighborhood apartment that we inherited from my grandparents, who moved to Israel from New York City in the 1950s. That is where I lived while in Jerusalem. In the mornings, I frequently would go to the Shacharit morning services at the shtiblach nearby.

The shtiblach was a veritable prayer mall, a busy set of connected, one-room prayer-halls in a modest neighborhood building. I would often see the saintly Rav Aharon at one of the services there. I would sit near him and thereby join him de facto at prayer. That would lift my spirits for the day.

Because Rav Aharon embodied the ideals of a primary archetype of praying, I considered him to be a remarkable model of prayer, of study, of teaching, and of Jewish living. For me, Rav Lichtenstein was the greatest rabbi of our times. He died on April 20.

Is the Kosher Light Switch Really Kosher?

Is the Kosher Light Switch Really Kosher?

Rabbis are fighting over the new device called the Kosher Switch.
VIN news reports at length on the controversy.
New York - A new light switch that has been under development for several years and claims to be approved for Shabbos use is one step closer to being available to the public, but whether or not the device is actually halachically acceptable has become the subject of debate over the last several days.

A crowdfunding campaign on Indiegogo  raised $50,000 for production of the UL certified switches, which developers say skirts any issues of chilul Shabbos by randomizing electrical impulses generated by the switch, within four days.  A video explaining the purpose and workings of the device garnered more than 90,000 views on YouTube over the same time period...
Note: I have had problems with one Indiegogo invention that I supported - a smart watch that never delivered on its promises. This suggests to me that Indiegogo has low or no standards to verify the claims of the developers who use the site. Accordingly, from the standpoint of technology and Jewish law, beware of putting your money into a non-existent and non-verified device.

Is the Shabbos Smartphone App kosher?

Yes, the Shabbos App is kosher. At first I thought it was a joke or a spoof. But sources say it is real. It is an app for a smartphone that makes it kosher to use it on Shabbos (the Sabbath).

Alas, the excessive $49.99 price for the app on Google Play is not so kosher.

The Fink or Swim blog has a thoughtful post on this matter.
...To me, it’s real simple. No one would have thought of the Shabbos App or the need for the Shabbos App if people were enjoying the break from technology that Shabbat affords. If we all loved being off our phones for 25 hours, the Shabbos App would be superfluous. No one would want it. No one would care to have it. But that is not the reality. Many people struggle with observing Shabbat every week. The phone is a private and quiet way to escape Shabbat observance. That’s one the many allures of the smartphone. It’s like holding the universe in your hands, and if someone is feeling stifled by Shabbat observance, the world in one’s hands can feel quite liberating.

I think most people who have smartphones would be quite happy to be able to use them 24/7. It’s a bit of a challenge to restrict one’s smartphone usage for 25 hours if one is accustomed to using their device on a constant basis. It’s not addiction as much as it is a habit. Smartphones have become like appendages to our bodies. They accompany us to the kitchen for recipes and culinary inspiration. They come with us to the dinner table and can be used to research a point of discussion at the table or to share a YouTube video that gives everyone a good laugh. They are part of our Torah study routine with the entire Torah available at the tap of a finger. Calling us addicts completely mischaracterizes the challenge. Our devices are like auxiliary brains. They are part of everything we do during the week.

So when Shabbat arrives, it is certainly a challenge. Some people embrace this challenge. They say that Shabbat is meaningful because they love being free from technology. It’s still a challenge, but the personal satisfaction and ecstasy of freedom makes it worth meeting the challenge head on. Others just accept the fact that they might be miserable without their devices and slog through Shabbat like zombies. Then there are the people who don’t think it’s worth giving up their smartphones for Shabbat. The pain of abandoning technology for 25 hours is greater than the payoff of keeping Shabbat. Those people have no incentive to turn off their phones for 25 hours. Why should they?

That is a tragic commentary on our Shabbat experience...
Talmudic analysis: I agree with much of this post and discussion. However, I do not approve of the use of the word tragic for discussing this matter.

It's hard to argue with those who say that Orthodox Shabbat restrictions across the board by any measure are heavily onerous. To preach that they are liberating is dangerous since many people will disagree on the basis of common sense and nothing else.

The sudden appearance of powerful personal technology like the smartphone casts a bright spotlight on the claim that the Shabbat wilderness experience is something that is good for all Jews, every week. It's a tough claim to defend in any day and age, and it now is tougher.

Is the Yo App Jewish?

Yes, Bloomberg reported that the incredibly popular, quirky and eccentric Yo app was invented by Jews in Israel.

Accordingly I'm awarding the app the Harris Epstein prize for great Talmudic inventions.

Stephen Colbert joined the Yo revolution with this take on it.



This reminds me of a song I heard as a kid at the first Broadway show I went to, "Milk and Honey". So I adapted the song lyrics for the app generation.

Yo, Yo,
You'll find Yo
The nicest greeting you know;
It means bonjour, salud, and skoal
And twice as much as hello.
It means a million lovely things,
Like peace be yours,
Welcome home.
And even when you say goodbye,
You say goodbye with Yo.

It's a very useful word,
It can get you through the day;
All you really need to know,
You can hardly go wrong,
This is your home as long as you say:
Yo,
The nicest greeting I know;
Yo,
Means twice as much as hello.
It means a million lovely things,
Like peace be yours,
Welcome home.
And even when you say goodbye,
If your voice has
"I don't want to go" in it,
Say goodbye with a little "hello" in it,
And say goodbye with Yo.

It's the most amazing thing
That I think I've ever heard
Wait till Berlitz hears of you
All my foundering's done
I'm a native with one little word

Yo, Yo,
I find Yo
The nicest greeting you know;
It means bonjour, salud, and skoal
And twice as much as hello.
It means a million lovely things,
Like peace be yours,
Welcome home.
And even when you say goodbye...
If your voice has
"I don't want to go" in it,
Say goodbye with a little "hello" in it,
And say goodbye with Yo.
