Professor Brian Cox: Quantum physics 'is not difficult'

I’m not really listening to this, because I have a very bad attention span and I am familiar with classical-quantum differences already, because it’s so interesting and I have to take exams on it.

Contrasting the common sense of classical physics with counter-intuitive quantum physics is fascinating and just one of those cool things about science.

I’m writing an essay on absolute zero for 10% of my thermodynamics module. The other two options were “thermoeconomics” which frankly sounds made up, and “classical thermodynamics in 20th century literature” which I would have tackled had my book collection not been at home.

It should be fun, I’m going to discuss theories of cold back in the 17th century and the crazy quantum things that happen when you make gases very very cold.

matthen:

Today is the 76th anniversary of Emmy Noether’s death, a woman whose contributions to mathematics lead Einstein and Hilbert to consider her as the most important woman in the history of mathematics. I know her from Noether’s Theorem, which basically says that symmetries in physics lead to…

I don’t know much of Emmy Nother’s work, and I keep meaning to change that. She sounds like an amzing woman.

Anthropic principle

I love finding out there’s a theory for thoughts I’ve been trying to articulate.

"In physics and cosmology, the anthropic principle is the philosophical argument that observations of the physical Universe must be compatible with the conscious life that observes it. Some proponents of the argument reason that it explains why the Universe has the age and the fundamental physical constants necessary to accommodate conscious life. As a result, they believe that the fact that the Universe’s fundamental constants are within the narrow range thought to allow life is not remarkable.”

Not by the Direct Method.: Sofia Kovalevskaya.

jessnevins:

Sofia Kovalevskaya (1850-1891). An important mathematician in the second half of the 19th century, and the most important female mathematician of that time. 

Also, a nihilist from her early teens, a participant in the Paris Commune, a lifelong advocate for violent revolution, an un-indicted co-conspirator in her husband’s real estate and stock swindles, and…wait for it…spent time in the last few years of her life inventing, and I quote, “unusual electrical machinery.”

We need an alternate history written where she survives the influenza that killed her, moves to the U.S., and teams up with Tesla. Or Moriarty. Or both.

Ironically, youtube is both saving and ruining my degree.

This just got posted on the facebook group for my maths lectures, it’s pretty hilarious.

Epistemological anarchism

"Epistemological anarchism is an epistemological theory … which holds that there are no useful and exception-free methodological rules governing the progress of science or the growth of knowledge. It holds that the idea that science can or should operate according to universal and fixed rules is unrealistic, pernicious and detrimental to science itself.
