Bedtime Story


How the Sun Shines


Hans Bethe did not waste his time at the conference.

At the conference was another mathematical physicist Charles Critchfield who would later do his PhD under Edward Teller.

Along with Critchfield, Bethe sat down and thought of the possible reactions in the sun that might follow the proton-proton chain reaction.

By end of the conference they both worked it out and jointly published a paper in 1938 in the journal Physical Review.

If you see the reactions above, they do go beyond helium but still end up in explaining only the origins of only Lithium and Beryllium.
The origins of heavier elements were still elusive.

It must be brought to your attention mon ami that astrophysics was not the area of interest of Hans Bethe.

Yet one must note that the science of big, i.e. astrophysics and the science of miniscule, i.e. nuclear physics are intimately related.
Once again I need to emphasize nature does not come in subjects of artificially divided different sciences.

Bethe on returning to Cornell began to think deeply about this topic of solar chemistry and sun’s source of energy.
Unlike Ralph Alpher and Gamow, he was not thinking on the lines of origin of elements but more on the working of the sun and to explain its composition.

Our sun was shown experimentally to contain traces of carbon, nitrogen and oxygen yet it was still unexplained how.

The very next year in 1939 working once again with Critchfield, they had it worked out!

In just a year!

By the way mon ami, if you think these silly, non-productive, good-for-nothing men were essentially just theorizing dreamy ideas about the workings of stars, you could not be more wrong.

Uncle Sam would use the services of all these mathematical physicists in a surprising manner far far away in the mountainous terrain and desert state of New Mexico.

Good night mon ami and my fellow cousin ape.
                 
Another great educator and teacher that I am aware of is Professor Subhashish in Bangalore, India.

While I narrate stories, he actually does and teaches real mathematics and physics.

He started the participation of Indian students at the International Physics Olympiad.

Do visit him here:


All his books can be downloaded for free through this link.


For entertainment may I suggest Kids Songs channel.



The Los Alamos County in the state of New Mexico had at one time (or perhaps still has) housed the greatest mathematical physicists in 1930s and 1940s


In 2010 its population was a mere 17,950 with lowest level of child poverty compared to any county of the United States
