video for String Theory




I ought to add here that to really get to String Theory, one ought to get through Quantum Mechanics and Quantum Field Theory first. [ Even though QFT is different than String Theory still, it is hard to understand Strings without first having a background in QFT.]

The Infra Red Telescope of NASA will be looking for planets that are possible for humans to live in.
When was the Infrared telescope invented?

This would be the first of its kind invented by Philip  Rosenblum.


The question however is even after finding a new world, how to get there? For that we need to study String Theory. This is to be able to find some crack in spacetime=some way of making a worm hole. After all, we can not go faster than light. So to get anywhere in our galaxy, we need to skip over [or under] space time, not go through it.

Now there is some kind of fundamental existence that is not space or time. This is actually stated in Lemaitre who discovered that the universe is expanding. [Friedman discovered that Einstein equations do have solution than can expand or contract.] 




Anti Enlightenment started almost at the same time as the Enlightenment. And Allan Bloom claims that this difficulty is what is at the root of the malice and sickness in the universities.

But he leaves out Kant and Hegel. Why? [I think that he must have thought they did not solve the problem-- even though clearly both meant to.]

I wrote all this before so why am I repeating this? Because of an added thought that Friedrich Jacobi  was on the opposite side of the Enlightenment and it was his idea of faith [or immediate knowledge [not through reason] and not through the senses] that was a target of Hegel.
This is in spite of the fact that both Kant and were trying to get to God--the Absolute Spirit.
But they thought that subjective faith was not the way.

The other interesting thought is that the root of this difficulty in some way I think was even back in the Middle Ages when the conflict between Reason and Faith was a major issue. But in the Middle Ages it was thought that there must be a way to synthesize them.



Rav Nahman of Breslov had a wealth of great ideas and advice but his main emphasis was on medicine for people's soul's. Medicine is not the same as food. So while Rav Nahman has great advice for particular problems, that does not mean to simple decide "to be Breslov". You might ask what is wrong with that? The problem is it is like a kid walking into a pharmacy, and picking out all the different medicines that have pretty colors.  Is there any question about how long this would last?

That is why I tend to emphasize the Gra and the Musar approach of Rav Israel Salanter in order to have an idea of the basic structure of Torah. Then within that context, Rav Nahman can be very helpful.

I learned a lot from my experiences at Shar Yashuv in Far Rockaway and the Mir. And I learned a lot from the great sages, Rav Freifeld, the founder of Shar Yashuv and Rav Shmuel Berenbaum. I mean to say it was not just book learning, but also I stuck around these great sages and thus learned a lot by osmosis.

[However it was not until later when learning with David Bronson, that the basic in depth learning approaches of Shar Yashuv and the Mir began to sink in.]]


[Rav Nahman emphasized learning fast and Litvak yeshivot emphasize learning in depth. So what is best in balance. To have some sessions fast and others in depth.]
