Belief in God is rational. Everything has a cause. So unless there is a first cause, then you would have an infinite regress. And then nothing could exist. Therefore there must be a first cause. Therefore God, the first cause, exists. QED.

Even though I think that learning Torah [Gemara Tosphot Maharsha] is the greatest of all service of God the environment for this activity is a Litvak Yeshiva but for some reason I have never been able to find my place in any such institution. So as second best, I try to do this at home. But it is hard to match the energy of an authentic Litvak Yeshiva --the energy that one gains by sitting in one and learning.
At some point I realized I was not welcome in the yeshiva world. So just from pure desperation I went to the Polytechnic Institute of NYU and majored there in Physics. After all I needed some way of making a living and had discovered a little before then the opinion of many Rishonim that Physics and Mathematics are a part of learning Torah. This is the opinion of many Rishonim, but you can see it most clearly in the Rambam in Laws of Learning Torah where he says - ''The things called 'Pardes' are in the category of learning gemara.'' And what is 'Pardes' they are defined by the Rambam in the first four chapters of the Mishna Torah and at the end of those chapters he writes the things discussed in these four chapters are in the category of what the Sages called 'Pardes'.'' [Those 4 chapters are Aristotelian physics and metaphysics. The Rambam is even more explicit in the intro to the Guide where he says the things are what the Greeks called physics and metaphysics.]
[I had been at the Mir in NY but then came to Israel. My time at NYU was after all that.
I also think that to learn Musar on Rosh Hashanah is important. Also that even though it is unspoken, it must be that Reb Israel Salanter must have had in mind the fact that strange an foreign trends were taking over the world in general, and the world of Torah in particular. So he saw Musar as a cure for the evil doctrines that were taking over in the world of Torah. [''Musar'' refers to the books of ethics written mainly during the Middle Ages]

There is an argument about when to celebrate the festivals. Generally, people go by the calendar introduced by Meton in Athens. This got accepted during the middle ages as being ''halacha leMoshe miSinai'' [given to Moses at Sinai.] [note 1] However it is not mentioned in the Gemara [Talmud]. My approach is go by Tosphot in Sanhedrin page 10 side b where the molad [conjunction of the moon and sun ] is considered as the start of the new month.
[When the Talmud says that nowadays we know the time of the new moon in several places it does not say anything about the calendar. It just says we know the time. nor is Hillel II mentioned in the Gemara in connection with any calendar.]]
So that the day of the molad is rosh hashanah. And the best way to celebrate rosh hashanh is to learn Torah. [i.e. to spend the day learning Gemara, Tosphot, Maharsha, and the Avi Ezri of Rav Shach]
[note 1] In the responsa of the geonim there are plenty of dates which do not correspond to the calendar--thus showing that the calendar was accepted later.
i have been pondering a difficult section in the Avi Ezri of Rav Shach that brings a question of Reb Chaim of Brisk. The issue is a courier brings a divorce doc and says, "In front me it was written and in front of me one witness signed." Rav Huna said either all in validation of the doc or all by the decree of the sages [that said he has to have seen both witnesses signing.] Reb Chaim of Brisk asks that we see in Bava Batra pg 165 that one witness verbally and one in writing is considered a valid validation of the doc. [So what is the objection of Rav Huna? after all, it has been validated. ]Rav Shach brings a Ran [Rabbainu Nisim] that says one witness verbally and one in writing is considered a valid validation only when it does not concern laws that involve felonies that result in physical punishment. It applies only in cases of monetary disputes .
