Almost 10 years ago, Leon van Dommelen (who taught Nanotechnology) addressed Engineering students in his 5th edition of Quantum Mechanics for Engineers, and said that, "on quantum scales it becomes clear that classical physics is simply wrong. It is quantum mechanics that describes how nature truly behaves; classical physics is just a simplistic approximation of it that can be used for some computations describing macroscopic systems; not too many of those, either and it is the same story as physicists tell their own students. Quantum mechanics is inherently mathematical, but the goal is to know enough mathematics to gain insight into quantum mechanics but not get side tracked with clever mathematical manipulations that have absolutely nothing to do with physical understanding. Engineering graduate students find too often themselves caught up in nanotechnology and typical engineering education does not provide anywhere close to the amount of physics one will need to make sense out of the literature in nanotechnology".

Best of the rockets achieve an efficiency of just 15%; not any different than our cars! Conventionally, it's understood that for every 5kgs of payload to escape Earth's gravity, a rocket has to carry 95kgs of fuel!

Nuclear powered rockets will be able to escape the curse of rocket equation but significantly increase the risk; howerver with incremental progress we have made in technology in recent years, particularly in computing, we may be finally ready to revisit and tackle the engineering challenges.

An update of 50-year-old regulations has kickstarted research into the next generation of rockets. Powered by nuclear fission, these new systems could be the key to faster, safer exploration of space.

Finding planet 9 that's six times the mass of 🌎......."Computationally intensive but we're up to it". The goal of science is to make new predictions.

Astronomer Mike Brown is best known for driving demotion of Pluto to dwarf planet. Here, he discusses the next horizons in astronomy, at least in our solar system, what to look for when hunting for life on other worlds, and where we might find the elusive Planet 9.

Professor RDR taught Advanced Quantum Mechanics & used JJ Sakurai as reference material. His ability to communicate science was enviable. Each week his lectures engaged all 85 spell-bound graduate students for a full 100 minutes, taking them through the journey building from the FIRST PRINCIPLES* step by step, bringing them to current week's topic.

*Elon Musk co-founder of , , , , ... often refers to reasoning from first principles as a physics way of thinking.

Foundations of Quantum Mechanics is written in simple and elegant style. Mathematical derivations are presented in complete detail with a lucid discussion of their physical significance. Symmetries inherent in quantum systems are brought out in a lucid way. Salient Features: The first chapter provid...
