This is a video of the 'barking dog' chemistry experiment captured with a high speed camera. When you watch it in real time, the flame appears to move quickly and directly the bottom of the tube. However, when viewed in slow motion, it shows that the flame actually gradually moves down the tube...
Gene therapy consists of modifying the DNA sequence to replace the gene coding for the disease with a healthy gene. Germ line gene therapy does this by targeting the germ cells; this means that once the egg is fertilised, every cell which descends from the egg contains the modified gene, and...
If light is electromagnetic radiation, when it reflects off objects and travels to our eyes, how is the information of the object carried?
Is it because of dispersion? Does light travel at different speeds depending on what part of the object it reflects off to help our brain form colours and...
Thank you for your response. The exams are over the May/June period, so I don't think there will be any resits until the year after, and I hope to start my A levels in September. I haven't listed IGCSE Biology, as I've already taken it this year. I do think you're right in saying that I should...
Hello,
I live in England, and in the future I would like to study physics or neuroscience at university. I am currently taking my GCSEs, and I have a dilemma with some of the courses I am taking:
I'm taking a Science GCSE course which includes Biology, Chemistry and Physics, and I am also...
Thank you for your helpful response. I have read of the 8 electron situation from GCSE and IGCSE textbooks, and as this is a quantum mechanical effect it is probable that it has been simplified for all young students.
I have read from a few sources that an atom's third energy level can sometimes hold 8 electrons, and other times hold 18.
In atoms which possesses enough electrons to exceed the the third energy level, what exactly is it that determines the amount of electrons this energy level can hold?
When an object's state is determined and ultimately decided as one, what happens to the wave functions as the property of the object is determined?
The Copenhagen interpretation suggest that the wave function "collapses" into one.
The many-worlds interpretation suggests that each possible...
I am very interested in physics, and so naturally I would like to teach myself the necessities of calculus, in order to allow myself to understand physics more.
Could anybody recommend any videos or books I could get started with?
The Schrodinger's cat thought experiment provides two possible outcomes in the many worlds interpretation; it is dead in one universe, and alive in the other. There are however many other possibilities of what could happen; there are wave functions concerning the positions which the cat may...
