How do we know neutrinos exist


I was wondering today why should we postulate neutrinos and make life more complicated than it already is.



This article explains why neutrinos are required and in addition as a bonus explains how they are detected. Apparently it is must for accounting for conservation of energy in beta decay.

Income inequality of US or hail capitalism US style!


This is from wikipedia and made me fall out of my chair!

  1. Top 1% owns 35% of wealth.
  2. Top 5% owns 60% of wealth or 3 out of every 5 dollars.
  3. Bottom 40% owns  just 0.2% of wealth.
  4. Bottom 60% owns just 4% of wealth or 96% is owned by top 40%
Really hail capitalism US style - 60% is poor because they don't try and Big banks/wall street firms will get saved by government if they fail [of course with fat bonuses for their executives].

Is there an opposite of absolute zero temperature?




That is do we have a highest possible temperature in the universe?

We know we have a lowest possible temperature  [−273.15° Celsius] when all particles of the system have no kinetic energy at all.

I was wondering is there an opposite of absolute zero and looked up in the net.

These two articles discuss this. Apparently it goes to the heart of physics!

Current contender is Planck temperature at

PBS - absolute hot
