My point is the learners need to think about it first and when they are stuck, steps are then provided. It is like doing a question. The setter or lecturer need to ask good leading questions or hints to guide the students in deriving the necessary relationship.

It has nothing to do with visual learner or auditory learner. I am quite surprised that people are still hooked up of the different learning styles thinking where a lot of research has already shown that it does not "really" exist.

By the way, this is just my viewpoint. I believe that there will be people who would not agree with me. I am good about it.

Can I ask what is this formula that you are trying to derive?
Length contraction

I doubt that this is length contraction formula when I replace the by .

Length contraction should be

Unless UK has a different notation or I misinterpreted your formula.

I was dividing the original length by gamma

I am surprised that you use Pythagoras theorem to in deriving this formula. I thought normally Pythagoras theorem is used in deriving time dilation. Again I may be wrong.

I think Pythagoras is used to calculate gamma, which is then used to calculate both length contraction and time dilation

So, finally watched it. So, anti-quarks are come into being when the bound of the quarks to the gluons is broken? what has to be done that a quark is able to escape? glouns have strong attraction to quarks to hold them together, if I am not mistaken.

Quarks and anti quarks can be made from a variety of interactions and at a variety of energies.

Quarks cannot "escape" as such because they cannot exist on their own due to something called colour confinement (think of the different colours adding to white - it must always be that way).
10. I'm currently intrigued by the question 'what is time?'

It is not possible for quarks to escape due to something called quark (or colour) confinement, although there is a weird state of matter called a quark-gluon plasma which occurs at really high temperatures where quarks and gluons can be temporarily 'free'.

https://en.m.wikipedia.org/wiki/Quark-gluon_plasma

As the link states, it is possible to get quarks on their own, but they are very unstable, and after a few fractions of a second they will form hadrons and gamma rays.

The temperature required to create a Quark-gluon plasma is 2 trillion Kelvin (2,000,000,000,000 K). At this temperature pair production takes place and quark-antiquark pairs are produced. The highest temperature reached at the LHC is 5.4 trillion Kelvin (5,400,000,000,000 K), which is still too low for the quarks to truly be free since the strong charge still has some effect.

Thank you for informations and oh gosh! these temperatures are unimaginable high! even nuclear fusion does not need such high temperatures. And this temperatures are just required to be free for a very, very, very short while. The forces have to be incredible strong, no wonder, these ones are holding the basics of all subparticles together. Without them, nothing would exist.

I know right

It's terrific!!!

Interesting to see that they are planning to use Hubble and the JWST together to make mini 3D movies of the outer planets to help inspire the next generation

Yeah, read it. Interesting indeed. Maybe this is the end of sondes and satellites for searching and obervating planets, if the hubble and JWST method is good enough to get many informations and details about planets.

By the way what does JWST mean?

Indeed it is interesting

JWST = James Webb Space Telescope
