Three last Susskind’s lectures on general relativity

… that is, lectures 10, 11 and 12: gravity in 4+1 dimensions, dynamics of scalars in curved spacetimes (and behavior of gravitational potential – which is scalar), a bit of topology (Euler characteristics), Lagrangian of a relativistic massive point particle, geodesics in curved spacetime and, finally, Schwarzschild solution.

On Harvard – again

By the way, why Harvard is called Harvard? Who is it named for? I guess, everybody knows that, but for me – it was a discovery of the day. It was named for English clergyman John Harvard. Mr. Harvard together with his wife has moved from London to America in 1673. He became a clergyman [...]

Biocentrism: book review

I was asked to review the book by Dr. Robert Lanza called “Biocentrism: how life and consciousness are the keys to understand true nature of the Universe“. If you are a scientist good enough in your area of expertise, at some point you start wondering whether you can explain everything around you, every single event, [...]

Michio Kaku on artificial intelligence

Nowadays, it is fashionable to hypothesize that an advanced AI, when it appears, will wipe pathetic humans out of the face of the Earth (risk of unfriendly AI, as transhumanists like to call it). I think, what’s not taken into account in these considerations is that humans will evolve as well, will be willing to [...]

How many scientists fabricate or falsify their research?

This is the title of a rather intriguing paper recently published in PLos ONE. As it turns out, approximately 72% of researchers have seen at least once how their colleagues used inappropriate or incorrect methods of research. The study by Dr. Fanelli contains analysis of 28 polls offered for answer to actively working scientists. Among [...]

An exoplanet near ultracool star

New record in astrometry and exoplanetology – the authors of 0906.0544 are talking about discovery of the planet in the vicinity of a very light star. The mass of the star is about 0.07 Solar masses, i.e., equivalent to 3-9 Jupiter masses – it is actually near the lower mass limit for an object to [...]
