touch (responsibility)
the maor eynayim brings the phrase from chazal "da mah l'maalah mimcha" (lit. "know what is above you") and explains it's deeper meaning: "know that what is above you, is from you." (mimcha has the alternative meaning of 'from you') he explains the meaning of these words: the arousal from below brings about the arousal from above. God's attributes are waiting to be awakened by your awakening those same attributes within you. i take away from this: if you look for strife in the world, you will find strife in your world. if you share love in your world, you will find the world full of love. and it is true for everything: patience, stress, hostility etc. [incidentally, this is the rebuttal to the argument put forward in the beginning of plato's republic.]
touch (silence is golden)
R' shlomo carlebach teaches (in a torah about purim) that the things that are the most pure and true remain unspoken. similarly R' akiva tatz explains that in judaism we must contemplate ideas a long time before we speak them. in essence (to my eyes) judaism is about reaching the depths of reality. when we touch these places, we need to draw out the truth slowly.. like someone on first waking squints to moderate the bright morning sunlight.

touch (God's pain)
we are told by our Rabbis "more than the calf wants to drink, the cow wants the calf to drink." I understood this to mean: just as the cow suffers if the calf doesn't nurse, so too, God wants so much to give us good, that if we aren't willing to receive it, it "causes him pain." We need to be open to the good that God is always ready to bestow upon us.

touch (21 av 5765)
before God allows a tzaddik to attain a new level, he first takes away his previous level. this is the meaning of the passuk in mishlei - a tzaddik falls seven times and arises. the tzaddik must maintain his faith that this loss, this fall, this mini-death is in order to receive even greater revellation from God. thus, through his faith, the tzaddik will rise--the opposite of falling which is like dying. through his faith a tzaddik lives.

touch (for the holy arizal's hillulah)
you've never seen anything like it
the amazing thing was the noise--no one shouted, no one shoved (that i could see anyways), the pushing was polite 'i'm here don't crush me' pushing.. but there were so many people it was loud to the point of overwhelming. in the end we went to king david's tomb[getting out through shaar tzion was quite a challenge of patience and will power], where we couldn't see anything because of the trees, but we could hear people from all over.. it was sooo many people. it must have been close to midnight before all the traffic had cleared out.
we were rescued by a really kind and unusually well-mannered police man and a cab driver with enough personality for 10 people.

Interesting DNA research
As the DNA 'alphabet' contains four letters - called bases - there are as many as 64 three-letter words available in the DNA dictionary. This is because it is mathematically possible to produce 64 three-letter words from any combination of four letters.
But why there should be 64 words in the DNA dictionary which translate into just 20 amino acids, and why a process that is more complex than it needs to be should have evolved in the first place, has puzzled scientists for the last 40 years.
---
One of quirks of the genetic code is that there are groups of codons which all translate to the same amino acid. For example, the amino acid leucine can be translated from six different codons whilst some amino acids, which have equally important functions and are translated in the same amount, have just one.
---
The University of Bath researchers suggest that the primordial 'doublet' code was read in threes - but with only either the first two 'prefix' or last two 'suffix' pairs of bases being actively read.
By combining arrangements of these doublet codes together, the scientists can replicate the table of amino acids - explaining why some amino acids can be translated from groups of 2, 4 or 6 codons. They can also show how the groups of water loving (hydrophilic) and water-hating (hydrophobic) amino acids emerge naturally in the table, evolving from overlapping 'prefix' and 'suffix' codons.
---
The theory also explains how the structure of the genetic code maximises error tolerance. For instance, 'slippage' in the translation process tends to produce another amino acid with the same characteristics, and explains why the DNA code is so good at maintaining its integrity.
---
The new theory also highlights two amino acids that can be excluded from the doublet system and are likely to be relatively recent 'acquisitions' by the genetic code. As these amino acids - glutamine and asparagine - are unable to hold their shape in high temperatures, this suggests that heat prevented them from being acquired by the code at some point in the past.
---
"As the code evolved it has been possible for it to adapt and take on new amino acids. Whether we could eventually reach a full complement of 64 amino acids I don't know, a compromise between amino acid vocabulary and its error minimising efficiency may have fixed the genetic code in its current format. "

what i want to know is how does this relate to the hebrew letters which can be seen as 22 unique entities, encoded by a 5-'letter' encoding alphabeth. [in some sense there are 5 bases (incl. uracil which isn't exactly a different base), and potentially more amino acids, but still how does it all relate?]

World-Wide Shema
An appeal has been made to every Jew around to world to simultaneously read the first lines of the prayer known as Shema: "Hear O Israel, The L-rd is Our G-d, the L-rd is One" on Wednseday.
The prayer is intended to ask for Divine help to prevent violence toward the planned expulsion of Jewish residents from Gaza and northern Samaria and for Divine intervention to cancel the plan. The prayer is organized under the motto, United We Stand, Divided We Fall.
The prayer will be recited at 9 p.m. Wednesday at the Western Wall (Kotel) in Jerusalem, at 2 p.m. in New York, and 11 a.m. in California.
Children around the world also are being asked to pray together the following night, one day before the beginning of the new Hebrew month Av. Former Chief Rabbi of Israel Mordechai Eliyahu will lead the Thursday night prayer at the Western Wall.
An unidentified group of women initiated the call for the children's prayer, which will take place at 7:30 p.m. in Israel (12:30 p.m. in New York); they are encouraging children to attend the prayer rally at the Western Wall, where more than 20,000 children are expected.
