Seminar notes: Is Hydrodynamics Relevant to the Origin of Life?

We are attending at least 8 seminars for every semester. Here is a short summary of the most interesting one! This was an interesting talk mostly focused on the bubbles formed in ocean and relating those with the origin of life. The speaker mentioned the mechanical forces created by waves in ocean and pointed out …

Science policy is giving rise to open science or a new form of capitalism?

Here is a provocative paper recently published. I will add my thoughts when I’m done with reading.   http://journals.sagepub.com/doi/abs/10.1177/0306312718772086

Chemical bonds simulated with quantum computers!

“Quantum chemistry is the science of understanding the complicated bonds and reactions of molecules using quantum mechanics. The ‘moving parts’ of anything but the most-simple chemical processes are beyond the capacity of the biggest and fastest supercomputers. By modelling and understanding these processes using quantum computers, scientists expect to unlock lower-energy pathways for chemical reactions, …

Acceleration with stars

His idea is that an advanced civilization could build a sphere that emits waste radiation in a specific direction. This radiation would accelerate the sphere—and the star it contains—in the opposite direction.” I’m not sure about the process of building a sphere around ‘stars’, but the idea is very exciting. However, comparing the whole universe, …

Stabilizing fusion plasmas

Sawtooth swings—up-and-down ripples found in everything from stock prices on Wall Street to ocean waves—occur periodically in the temperature and density of the plasma that fuels fusion reactions in doughnut-shaped facilities called tokamaks. These swings can sometimes combine with other instabilities in the plasma to produce a perfect storm that halts the reactions. However, some …

Surface-bound hydrogen: diffusion > desorption

Wait! What? “The first step in hydrogen storage is chemisorption, wherein gaseous H2 collides with Pd and adsorbs (sticks) to the surface. Secondly, the chemisorbed H atoms diffuse into the sub-surface, several nanometers deep.” Why gold-palladium alloys are better than palladium for hydrogen storage

Math Cheat Sheet :)

It is always good to have such one throughout the university. This is for AME 60611 Math course. Although I have a terrible handwriting, still it is the best way to remember.
