A simple and clear explanation of all the important features of quantum physics that you need to know. Check out this video's sponsor https://brilliant.org/dos I have spent a lot of time thinking about how best to explain quantum physics and this is the result of all my hours of pondering, and I’m really happy with how it turned out. I decided to just explain it as it actually is, rather than rely on analogies. The video explains the quantum wavefunction, particle-wave duality, the measurement problem, the double-slit experiment, superposition, entanglement, quantum tunnelling, the Heisenberg uncertainty principle, and energy quantisation.

What existed before the Big Bang ? This question has always been a challenge for scientists but now it seems they have found the answer to it. But it has left scientists shocked as Brian Cox revealed that something terrifying existed before the Big Bang. So what existed before the Big Bang? Why has it left scientists terrified?

This chemistry video tutorial focuses on the Bohr model of the hydrogen atom. It explains how to calculate the amount of electron transition energy that is released or absorbed whenever an electron jumps from one atomic energy level to another. The electron transition energy formula / equation helps you to calculate the energy levels of electrons in the hydrogen atom only. This video also explains what is meant by the Lyman, Balmer and Paschen series. The Lyman series is associated with UV radiation. The Balmer series is associated with the visible light emission spectrum and the Paschen series is related to the infrared region of the electromagnetic spectrum. The bracket series and Pfund series are part of the IR spectrum as well. This video contains plenty of examples and multiple-choice practice problems.
