All the maths and science GCSEs and A-Levels I could get without breaking the timetable, and a shiny degree to top it all off.Wiccan child, what science qualifications (from GCSE's to university degrees) do you have?
I think they were Maths, Further Maths, Biology, Chemistry, Physics, and RE. You can only four, but my tutor was the guy who made the timetable, so let me double two up (FM and Physics, I think), which gave me a free slot, so I chose RE.Do you mind me asking which A-Levels you took?
ExactlyWhat's funny is I have no academic credentials. Just a few semesters of community college and that's it. Of course, I still think this is an advantage since it illustrates you don't HAVE to have a degree to understand science. As long as you have a thirst for knowledge and common sense... The credentials just mean you're unlikely to make a career out of applying what you know.

Sadly not. I found chemistry the hardest of the sciences - physics had clear, deductive reasons for the solutions to its problems, biology was interesting enough to be easy, but chemistry... it's so arbitrary! "To test for X you use Y until it does Z" - no reason, but just rote memorisation!Haha, wow that's a lot. Doing six is possible in most schools, but wow, that's one heavy timetable of some very hard subjects.
Did you take Salters Chemistry by any chance?
Ok ty. If I am in a train isn't my motion from that perspective stationary, but from the platform i am moving at such a speed x. Whilst on the platfrom the bystander appears stationary from his frame of reference and the train is moving at speed x.please clarify your question.
Correct. Motion is relative.Ok ty. If I am in a train isn't my motion from that perspective stationary, but from the platform i am moving at such a speed x. Whilst on the platfrom the bystander appears stationary from his frame of reference and the train is moving at speed x.
Photons travel at c from all inertial frames. That's the premise of Relativity.So to the photon, the photon appears stationary where as I, on the "platform" of the Earth, am moving at lightspeed to the onlooking photon.
Is that right or wrong?
What the photon 'sees' is a peculiar question. Does the universal speed limit cause warping of spacetime, or does the warping of spacetime cause the universal speed limit? Either way, the photon 'experiences' everything as static in time and two-dimensional - though different photons view different slices of space differently.If right, as only photons can travel at lightspeed, from the perspective of the onlooking photon, isn't everything else including me a photon too because it "passes bye" at lightspeed?
I imagine I will need somebut who cares if I learn something?

'Course, had I realised that was the problem at the time, I might've got my teachers to clarify... grr.
What about you? What did you do / are you doing?

Say that I microwave one Totino's Pizza Roll for like an entire, continuous month.
Would it eventually become radioactive?
Would it be poisonous if I fed it to my friend while he was sleeping?
Please don't mod report me.
I would stay clear of that junk food! cooked or not; it is unhealthy stuff to eat!Say that I microwave one Totino's Pizza Roll for like an entire, continuous month.

It would probably* burn to a crisp and after a while the microwave itself would probably* be damaged.
*I don't have the $$ to verify this experiment though, but if you wish to donate the funds I'd be more than happy to try it for ya
Okay. Here's one.
What would happen if you had a reinforced box with a lid on it that can be easily removed somehow.
Inside this box you detonate a stick of TNT but none of the pressure escapes.
What would be the result if I wrapped this box as a birthday present and then gave it to my friend for him to open?
Thank you.
Unfortunately my digital microwave only lets me nuke something for 99 minutes and 99 seconds at a time.
Poopers.

He would be squirted by high pressure fizzy sooty water, though he might also be hit by the flying lid or suffer Carbon monoxide poisoning. The explosive power of TNT is the sudden change in volume from a solid stick to high temperature and so high volume gases. These gases include Nitrogen Carbon Dioxide and a lot of steam. Store your explosion products in a reinforced box and they will cool, the water will condense, and the pressure of the gases decrease. When released at room temperature they would have a much lower volume than the hot gases produced in the explosion. But they are still contained in a box under much higher pressure than atmospheric pressure... as a result a lot of the gas will dissolve in the water. When the pressure is released this should fizz up immediately, Carbon is another of the reaction products and the sooty particles will provide plenty of nucleation sites for bubbles to form. Foul black poisonous foam will spray out. Bit like adding a mint to a bottle of Toxic Cola.
