I admire both, but I really like Witten. Which one of them have a chance of becoming the next Einstein in your opinion?

I wanted to build a diverse systematic reading list, and I don't have a science background (more english / humanities) but would like to develop this area of my knowledge--are there any books you would suggest that I get started on?

If yes, please give me some examples. Do all scientific theories are constructed based on inductive arguments?
thanks a lot

Some scientist believe there is a limit to how long humans live. One supporting argument is that during the last century life expectancy from age 65 has increased more slowly than life expectancy from birth. so eventually these two will equal. at which point according to scientists life expectancy should increase no further. In 1900 life expectancy at borth was 46 years of age. and life ecpectancy at age 65 was 76. In 2000 these figures had risen to 76.9and 82.9. respectively in both cases the increase in life expectancy has been linear. Using these assumptions and the data given find the maximum life expectancy for humans."

Do transitional fossils prove evolution? Does those who believe in evolution commit the logical fallacy of affirming the consequent?

Here is a quote from an article that I found on the website of California Academy of Sciences by the title" "Fish Out Of Water" the article states that "the bones inside animal’s forward fins provide evidence of arms in the making" Read the full article here: http://www.calacademy.org/science_now/headline_science/fossil_fish.php

So the argument is this as I understand it:
If evolution is true than transitional fossils will be found
The tiktaalik is a transitional fossil since it has a bone inside of its forward fins which provide evidence of arms in making.
Therefore evolution is true

An example of the same fallace:
If it's raining then the streets are wet.
The streets are wet.
Therefore, it's raining.

In symbolic form it looks like this

If p then q.
q.
Therefore, p

I was just a reading a question/answers about the Ouija board and I have always been curious to know if there was any scientific explanation as to how they work. I realize there may be many different opinions as to the authenticity of the game but I just need to understand what makes it move without the mystic/religious hoopla reasons. Mind you I have played the game in groups and in solitare and can't figure out how the answers make sense, much less how it moves. I know I didn't push it and yet it answered in a coherent manner.
