Gravitational waves

Me and Physics; don't make me laugh. I dropped out of Physics class in high school (3 atheneum). I can't even get Newton's equations right. Forget about General Relativity. What could I possibly make of gravitational waves? I am a man for History, languages, Law, in case you hadn't noticed. It just so happens that Law brought me to Sociology and Sociology to Logic of Science and once there, you roll from Popper to Einstein and back to Physics with renewed interest. Interest is one thing, but how in the world am I going to grasp all that if I couldn't keep up, right from the start?

In our time, comes to the rescue. Melvyn Bragg met with Jim Al-Khalili, Professor of Physics at the University of Surrey, with Carolin Crawford, Royal Society Research Fellow at the Institute of Astronomy, Cambridge and with Sheila Rowan, Professor in Experimental Physics in the Department of Physics and Astronomy at the University of Glasgow and they sorted it all out for me. I am not going to try to reproduce anything of their discussion here, no need to get audacious, but believe me, I didn't miss a second. This podcast is one of the very, very best there is.

Schug (סחוג) [s.ch.oo.g]

Schug is a spicey additive that has its roots in Yemen. You can mix it with sauces, salads and soups. My father-in-law used to make it at home after learning the recipe from a Yemenite Jew colleague of his. I asked him on occasion how he made it, but it was only several years after he passed away that I set out to reconstruct the recipe. Today I make a schug that is different from what I recall was his, but has developed in the direction my wife and I like it best.

green peppers
fresh cilantro leaves (Koriander, כוסברה)
lots of garlic
cumin
cardamom
black pepper
salt
olive oil
lemon

Every time I take the ingredients in different proportions. It really depends on the season and what I know of the quality, strength of taste, in the ingredients. Right now, because the warm season has started, I use more salt and oil to prevent early molding.
Clean four green peppers: cut off the top and bottom, throw away the seeds and cut them in easy to chop pieces and throw in a blender. Add one tea spoon of salt, one tea spoon ground cardamom, one tea spoon ground cumin and half a tea spoon fine ground black pepper and a spoon oil. Blend. Add a handful of cilantro leaves (100-200 gram) and seven cloves of garlic. Blend until the whole becomes a green paste. Add more oil and the juice of one lemon. Blend for five minutes.

KMTT -- The Torah Podcast

Podcasts are my means to perceive the world. On whatever subject I like to achieve more understanding, I look for a podcast. The KMTT podcast is among a handful, I follow for enhancing my knowledge about Judaism, be it religious, be it secular. KMTT was recommended to me by a religious acquaintance. He himself listens to the Hebrew version, which I haven't tried yet.
I listen to the English version, but not to all issues. I have a lack of interest in halachic matters, so I pass these over. What I pick are the theme episodes on Jewish thought and philosophy and the ones on the weekly Torah readings, parshot hashavua.

This week's parasha is parshat bemidbar and as usual I had a hard time following the whole lecture. No matter how much I like to see myself as a Jew, a secular one for that matter, in these traditional settings I feel like an anthropologist and a newbie at that. Alternately I feel, the way I felt in my first years at Law School when University Studies and Legal Thinking still eluded me. An inapt and scrambling outsider.

Nevertheless, I did pick something up. One of the things that is mentioned in parshat bemidbar is the special place the tribe of Levi has among the Israelites. The lecturer (Rabbi Yonatan Snowbell) discusses what meanings and sense this place, aides to the caste of priests, the cohanim, has. There seems to be a connection with the role the Levites fulfilled when the sin of the golden calf took place. They were the only ones who did not sin and they were appointed the task to kill those who did. (And some 3000 were killed, good old bloody Bible.) Then the task of aiding the cohen was taken away from the original appointee and given to the Levites.
Fine, but this raises a question of how this is justified. Is it because they did not sin or were they chosen to get the task all along. The whole thing comes to stand in a strange light if you take into consideration that Aharon, the cohen, had also sinned, not so badly that he needed to be killed, but nevertheless he did. Yet, he was not replaced from his office and the Levites were not placed over him, in stead became his aides. How is that for measure and equity?

When you are a secular it is easy to stay indifferent or just declare that such passage in the Bible doesn't make sense. When I was still busy as a legal professional, I saw that with matters decided by the Supreme Court or by the Legislator, you were intent on understanding and interpreting the law in an optimized way, but should you find a verdict or a statute that you cannot reconcile with the system of low, you are in a position that you can reject it.
A religious Jew, however, can never reject anything in the torah, hence he has to ingenuously reason around the whole text and persist endlessly to find sense. That is, from the perspective of secularity or of secular legality, a weakness, yet it is a strength by means of the resulting creativity and depth in the reasoning.
The end picture is that of a mixed one where both the sinner (Aharon with assignment to atone) as well as the righteous (the Levites) have their place and so it seems, the righteous as an aide to the sinner, who is to be the leader. Fascinating thought.

Chumus

It is no small feat to get your chumus salad right. However, these days I make new portions for our household every week and I no longer am intimidated by the challenge. I have established a stable quality that has found wide praise and I have found the secret ingredient: ... naah, that would be telling. :)

I have browsed through many a cookbook, I have interviewed orientals in the neighborhood, who wouldn't want to be found dead with a bought chumus salad in their house, I have searched the internet and nobody mentions the ingredient I have discovered -- and I find it indispensable. If you want to get your salad right, nice and creamy, nothing that sits like concrete in the stomach, you are going to need it. All right, I am going to divulge it anyway, so let's go and mention it here and now: I get my salad right with ... water. Yes, water, as simple as all that. I suppose tap water will do, but I use bottled water, for what it is worth.
The problem is not with the chumus, that is the chickpeas (Nederlands: Kikkererwten), the problem is with the tchina, that is the tahin, the paste of sesame seeds. If you make chumus the way sephardi grandma's or Arab food stall owners tell you to do it, the tchina makes the salad lump like heavy dough. What, if you ask, makes the salad creamy, is either not answered or if it is, you will use too much of the additive: lemon juice or olive oil or the water in which the chickpeas were cooked (or held in case you use a can). Once it was even suggested you need to separate the peas from their skins. For one that was an awful lot of work, and second: it didn't make any difference.
You need lemon juice in chumus to lighten up the taste, but use too much and the lemon gets too dominant and the salad is too sour. Olive oil, I do not use at all. I may add it to a serving, but on the whole I try to keep the calories down in what I cook. Besides, oil doesn't make for creamy salad, it makes for oily salad, which is a different taste and also oily is heavier in the stomach -- what we wanted to prevent anyway.
Now, the chickpea brew... Here is what brought me to water. You see, the water from the can is salted, not so tasty, ripe with additives you may not like in home-cooking and ... Hey, I do not use canned peas anyway. I buy them dry, I soak them for half a day and then cook. What happens during cooking, is, apparently, some kind of starch gets separated from the peas into the water. If you allow the brew to stand and cool down you will see the starch thickening. Needless to say this is also heavy on the stomach. In addition, I have learned to cook the peas with baking powder (sodium bicarbonate) and I wouldn't want that in my food.
Hence, I tried my hand with water and it worked -- perfectly. So here goes. My recipe for around 500 grams of chumus salad.

250 grams dry chickpeas
200 grams tchina טחינה גולמית=
1 tea spoon salt
1 tea spoon ground cumin
1 clove of garlic
juice of 1 lemon
2 tea spoons sodium bicarbonate
water

Soak the peas at least 8 hours in water and one tea spoon sodium bicarbonate. Skim the foam that is separated from the peas. Note that while soaking, the peas make popping sounds. Don't go looking for a leaking tap, or a scurrying insect, the noise comes from the peas.
After soaking, cook the peas with lots of water and one teas spoon of sodium bicarbonate for circa 30 minutes. Right from the beginning there will be a lot of foam you'll need to skim away. Next, stir while cooking and observe how some pea skins come floating about. They are tasteless; if you have the patience, remove as many as you can. When the peas get the right taste and smell take them off the fire and throw them in a sieve and rinse with cold water.
Put the peas in a blender with salt, garlic and cumin. Make an initial blend. Add the tchina and blend again. The whole will develop into a thick dough. Start adding water and blend till you approach the correct texture. Then add the lemon juice. Blend again and taste. Maybe you will want to add just a tad more water and then you are done.

Holy Sepulchre

Somehow it never happened until now. Today we drove to the old city of Jerusalem and this time, apart from visiting the Western Wall, for the first time in my life, after so many missed opportunities: I visited the Church of the Holy Sepulchre.
My old schoolmaster would have been proud of me, maybe hoping my soul is yet to be recovered for Christendom, but no such luck.
Just as the Kotel looks to me like a mere bunch of stones, the church of the HS looks like a dilapidated, anachronistic smudge. If I liked being there, it is only because it spoke to me on whole different level -- nothing religious or even spiritual.

What a weird place it is. A dark, amorphous dungeon, with numerous alleyways and niches and shady parlors on worn flagstones and filled with tourists, gazing pilgrims and the odd priest looking more like a prop from an Indiana Jones film than a proper priest. For example there was this crooked, young looking, skinny priest, with a long black beard and a crocheted black head garment. He had set up shop with a huge host of religious trumpery, almost impossible to make out, for there was so little light in his cramped alcove. He was devoutly praying in the way of a religious Jew from a prayer book with Arab script.
An Armenian priest with black robes and upside down top hat was energetically managing the entries into the Tomb itself, while chewing tobacco, or otherwise jawing and spitting about. Some pilgrims looked distinctly out of place, such as the Russian lady with flashing red outfit befitting a brothel, rather than a Church, or Dutch pedestrians, seated on the stairs in a yogi pose.

This looks nothing like the kind of Christianity I grew up with. Well, I know that, I am prepared for that. Never, when I visit some Christian site in Israel, I find light and sober Calvinist churches. If it looks like anything I once associated with something proper, it is the Roman Catholic stuff you find for example in Nazareth and on Mount Tabor. Over the years I have come to know also a little bit better the Greek style, not just in Israel, also as a result of journeying Greece. However, this looked not even much like that. The odd icon, perhaps, but it was all too dark and dirty. It was Armenian mostly -- with the Armenian script also dominating the walls around the tomb. And I had the strange praying priest pegged as a Syrian.

I am probably not going to be moved either, if it would have been Calvinists running the show, simply because I have strayed from the path too much. Apparently I am not susceptible to the mumbo-jumbo that is attached to Holy Sites. What struck me though and had me fascinated was how thoroughly Un-European this site is. If you think Christianity is a European faith, look at this holiest of holiest of it and you see nothing of it. Well, I suppose the majority of Christians aren't even Europeans, but if so, they are Africans, Asians, South-Americans, but this was not their atmosphere either. This was the atmosphere of where the Church originated: the Middle-East, or more precisely, where the Church as an institution originated: the Eastern Roman Empire. I felt as if I were in Constantinople before 1453 or even before 1099, before the Latin Kingdom of Jerusalem. That is what fascinated me.

Educational podcasts, a search.

Podcasts are extremely suitable for education. I have said it before, I am not the only one to say it, but just as with other podcasts: you have to know where to find them. Especially those institutions that put out their lectures as podcasts, apparently do that for their own students only and therefore invest no effort in making it known to the wider public that they are there. It is hard to find them on the internet, in podcast directories and other places where you might look. If you are interested to know what podcasts are offered by the various educational institutions in the world, you will have to look them up one by one or go through unfiltered directories and so on.

A case to bring this problem home is my History 5 podcast. I am on the look out for History Podcasts all the time. I have already discovered this series from UC Berkeley and figured it is delivered twice a year. I even came into contact with the professor who delivered it in 2006, but the 2007 series still eluded me until yesterday. Not for lack of searches, mind you. I queried the professor, I queried the iTunes directory (which so far got my marks for being the best source for searching podcasts) with no result.
Yesterday I stumbled into it and this was while discovering one old and one new place on the web that delivers some inventory of educational podcasts:
  1. Free Academic Podcasts
  2. Learn-on-the-go
I am off to learn History 5 again. This year, not with Thomas Laqueur, but with Margaret Lavinia Anderson. I have listened to the introductory lecture. Very different style from professor Laqueur, but I am sure I'll get used to it and I am eager in anticipation for getting the history of Europe 1450-2000 in a new style, per chance, from a new perspective, in any case with new insights.
