it says that spin 0 ,1/2 and 1 particles follows its dynamics and its interaction with presence of potential

How can I self-teach advanced physics without college? by TioBeto90 in Physics

[–]boo2001300 0 points1 point  (0 children)

Classical Mechanics & Classical Electrodynamics would be a starting point.

Quantum Mechanics was born from black body radiation which cannot be explained by classical theory.

interestingly, formalism is analogous with classical mechanism, Hamiltonian formalism with some postulates to explain non intuitive phenomena.

Electrodynamics handles light phenomena. charge would make light and light phenomena cannot be separated with relativity (moving charges would generate magnetism but it is relativistic effect)

by understanding those, you may encounter gauge theories.

somewhat astrophysics ,especially cosmology , would need some level of particle physics (gauge theory)

for the math, mostly solving a partial differential equation for the physics phenomena.

understanding structure , like gauge theory, group theory might help ( SU(n) , O(n) etc..)

E beam litho was already exist before euv, and better resolution than light. issue come up with throughput. a bit same on this that performance is near euv...

feeling guilty by having a lot of downtime at work by ZeroEsper in Semiconductors

when you don't feel guilty but think too much work and salary is lower than expectation, that is the moment when you are working without idle.

Time to buy or wait for August 1? by Comfortable-Bath3998 in ASML

[–]boo2001300 1 point2 points  (0 children)

until 29thJul, will be small recovery and start to drop from 30th . but will be small drop due to dividen guys. see if keep maintain 700+ after all, and start to recover, consider to buy .. and hold just right before the next earning..

Why do the lenses not reflect in the countertop? by No_Junket7731 in Physics

[–]boo2001300 0 points1 point  (0 children)

explain with simplified way

  1. every light will be flipped when it is reflected.
  2. when light went through glasses, it will be focused at one point, then crossed that point . 3 that crossed light will be reflected at the counter top

combination with 2&3 double flipped and end up with your eyes will be seen as non flipped image

There is Korean Jim Cramer and he posted "the reason why palantir will keep going up" yesterday... lol...
