Particle Physics: Antimatter

Sep 9, 2008 - you couldn't see it because nothing can travel faster than light speed - not even relative to another thing traveling at light speed thus no light rays from you could reach the mirror and so you couldn't see yourself.

Sep 9, 2008 - if you are traveling at light speed and you look into a mirror you won't see youserlf

Sep 10, 2008 - The L.H.C has found the equation to explain the universe!! I'ts 1+1=2 OMFG

cxdemon Says:

Sep 10, 2008 - The speed of light is relative so even if you were travelling at C light would be leaving you at the speed of light relative to you. so you would see a reflection,

tnuont Says:

Sep 12, 2008 - yes but it will need to reflect of the mirror and reach you and because your moving the speed of light it cannot catch up to yo and unless light goes faster or bends through time.

Sep 14, 2008 - No, not 1+1=2, wolverine005, the LHC is going to find the answer to life, the universe and everything: 42!

Sep 16, 2008 - if you are traveling at 100miles per hour you wont see yourself in a mirror either :D

Sep 16, 2008 - when i get my bedford running properly, how would you explain wot will happen when i turn my lights on, at just under the speed of light? and if i wer to over take the light and look back, will it be dark or will i see the light??

tnuont Says:

Sep 17, 2008 - You would actually see yourself since light travels much more faster than 100 mile per hout it would be able to catch you easily.

Sep 23, 2008 - math not hard, vision not hard to figure. What is hard, is the connections between different sciences

OnlyTruthCounts Says:

Sep 23, 2008 - That is an interesting remark,, I haven't thought about that one..

Fullperson Says:

Sep 23, 2008 - lol yea, you traveling at 100 mph, you don't see yourself in mirror. You see the popo, swat helicopters and maybe sparks coming out of your tires

Oct 2, 2008 - yes agree they have different sets of variables, i say govt must fund them either way, lets see what will unfold.

Dyynam0 Says:

Oct 5, 2008 - what?

HenryLascelles Says:

Oct 5, 2008 - that was really informative and actually resonably easy to understand! hope the lecturers are that good when i go to uni next year.... wont b doing physics tho... hardcore maths not my thing! btw zythepsarians comment is epic xD

Nov 8, 2008 - by my standards i feel that anti matter is an imagine way of felling 3 gigajewls per sec in you atomic/-/cosmiticular body in ways that motion is nott real and can or cannot exist in an after life it makes sense..

and1uprise Says:

Nov 23, 2008 - light always moves towards/away from you at 186,000mi/sec., whether you are standing still or moving. he explained this in the video, if you are traveling in the same direction as the light trying to catch it you will make no progress. so to two different observers moving at different speeds the photons are actually percieved in two different places.

Nov 24, 2008 - I have PhD from the University of Maryland College Park, in fiber quantum rabbit-hole mechanics with focus on determination.

Dec 7, 2008 - Sounds clever

Dec 9, 2008 - he's just semi- explaining observations. I hate when lecturers dumb things down. What do you mean by "physical state"? He does not know. I'm a physics major, just pointing out that anyone, even pros, can spit out what they've been told. But few actually understand what they are asking us to remember for their tests. Is this then actually education??

snapapple123 Says:

Dec 13, 2008 - i dont think he fully understands what he is talking about. he speaks loudly when he is explaining the math, but speaks very softly in explaining what it means conceptually. he keeps repeating, "if we had more time i could explain why this is so". if you dont have the time to explain it completely then dont waste other people's time in giving half explanations. this is the source of misconception. interesting idea, but very badly presented.

snapapple123 Says:

Dec 13, 2008 - i completely agree. i wont be able to understand every physics concept, but theres no point in just memorizing formulas and accepting everything as fact. i cringed everytime he said, "i would demonstrate this in more detail if i had more time". my favorite physics professor would derivate every equation, and explain concepts along the way. from this video, im guessing this is a strange way of teaching... actually understanding the material you are presenting.

marclab1 Says:

Dec 13, 2008 - Exactly why I want to teach this stuff... I applaud your pursuit for truth...

dannykanoista Says:

Dec 19, 2008 - Well probably he is explaining it to secondary school students...
