Why Bose is not the scientist after whom Higgs is named. Reply

A very few particles (out of 1000s) are named after scientists, eg the so called mu meson was called a Yukawa Meson, although it turned out to be a misnomer. Mu-meson was found to be a lepton, rather than a meson, as was thought by Yukawa and others.

Now called Muon it belongs in the same class that an electron belongs to, leptons, which are both Fermions. Hence initially thought to be a Boson (because all mesons would be bosons) the muon is actually a Fermion (all leptons are Fermions).

Should we say; initially muon was named after Bose, then correctly; after Fermi? That would be HOKUM. Right thing would be to say; it was named after Hideki Yukawa (wrongly as a meson or boson) then it has been named as muon which is now a Fermion. But its still named after Yukawa; given to a misnomer-correction. It can be called Yukawa-Lepton MUON (instead of Yukawa Meson Mu).

Nowhere Bose or Fermi have been the scientists after whom this particle has been named. Bose and Fermi are scientists after whom a principle of physics or nature has been named but not a particle. That would clear any mischievous air. More…

A particle that defies classical mechanics ! 1

A photon has no mass but energy and it has speed and it has momentum although it does not have mass. Thats impossible in Classical Mechanics. Because Classical Mechanics associates with every mass; momentum and kinetic and potential energy. All those would be zero if mass were to be zero.

Also the speed of the photon is constant while its energy and momentum are changing. This is unimaginable in classical mechanics. In CM first momentum can’t be defined from mass and speed if mass is zero, then while speed is not changing how is momentum changing? So both variables speed and mass fail to define a momentum for the photon, and not just the failure to have a mass. How then momentum is defined for this particle? Its not defined as long as photon is just a particle. Thats impossible. More…

A step toward Higher Education? Reply

Here is the summary. And I am quoting actual numbers from News Paper Reports.

News Report; 5% Odisha Resident students. [Including perhaps those also who would be Odia by their citizenship, irrespective of where they stay]

My estimate; a typical 10% general category students, going by how large the quota regime entails in terms of percentage toward quota qualifiers.

News Paper Report; Lying vacant per anum, 10%.

My reasoning; if there would be no quota based qualification system perhaps these seats would never lay vacant, plus we would have far superior engineers produced in the country. Because the 3-levels of quota scrutiny sees the merit off to such a level even 10% seats lay vacant, at the same level that gets admitted after fierce scrutiny. More…

What is it like to be in an Ivy League. Just a musing. Reply

The other aspect is from my own experience, while you are highly qualified, you are perhaps no more pouring in as much as even you would like to pour in, in terms of real research. You or your employers don’t want you to go into controversies, because they drain you out of wit and the employer runs into razor sharp issues. The Ivy Leagues have the “requisite infrastructure” which is cutting edge in a way preconceived notion kind of way. It really does not open the actual researchers to the issues involved in fundamental thinking. And sooner or later we all the highly intellectual kind belong to a level where we see our wit’s end. It takes the highly competitive experience of figuring out what exactly the Ivy League want from you for you and them to be successful lest which they are subjected to competitive and often no so harmless scrutiny from even tiny rats.

An interesting problem in elementary mechanics. Reply

Here is a problem on mechanics.

Problem; Two particles move in a uniform gravitational field with an acceleration g. AT the initial moment the particles were located at one point and moved with velocities v1=3.0 m/s and v2=4.0 m/s horizontally in opposite directions. Find the distance between the particles at the moment when their velocity vectors become mutually perpendicular.

Here is my ans. (Got to fig. it out in a concise way after scribbling through pages unsuccessfully. )
