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. Let me know if it was helpful! Cheers Dx

Further reading
For a more detailed introduction to quantum physics: 'The Quantum Universe' by Brian Cox and Jeff Forshaw is good.
And a slightly more advanced but fantastic description of what we do and don't know about quantum physics is the excellent book 'Beyond Weird' by Philip Ball.

In this video, we look at static electricity. We start by looking at how electrons can be transferred from one insulator to another to create a static charge. We then look at how this is applied in a Van de Graaff generator. Finally, we explore how static electricity can be dangerous and how we can prevent this.

Mind-Blowing Theories on Nothingness You Need to Know | Documentary

admin
1 Views · 8 months ago

Are you ready for a mind-bending journey into the concepts of 'nothingness' and 'vacuum'? This video delves deep into 8 fascinating questions that could revolutionize our understanding of the universe and existence itself. Prepare to have your perception of reality challenged as we explore the cutting-edge of physics and cosmology!

Does 'nothing' exist, or is there only 'quantum foam'?
According to quantum mechanics, even the most perfect vacuum isn't truly empty. We'll explore how the Heisenberg uncertainty principle and quantum field fluctuations show that 'nothingness' is actually a dynamic environment where particle-antiparticle pairs constantly pop in and out of existence. Discover the mind-boggling concept of quantum foam and how it challenges our classical notions of empty space.

Does "The Schwinger Effect" demonstrate "something from absolutely nothing"?
The Schwinger effect suggests that a sufficiently strong electromagnetic field can produce electron-positron pairs from the vacuum. We'll delve into this fascinating phenomenon and discuss how it might represent a practical application of Einstein's famous E=mc² equation, showing how energy can be converted into matter. Learn about the recent experiments using graphene that have brought us closer to observing this effect in the laboratory.

Can quantum fluctuation potentially create a universe from 'nothing'?
Quantum mechanics and inflationary theory propose that our universe may have arisen from quantum fluctuations. We'll explore the mind-bending idea that the entire cosmos could have emerged from 'nothing' and examine the theoretical frameworks that support this concept. Discover how the laws of quantum mechanics might allow for the spontaneous creation of space, time, and matter.

How Does Hawking Radiation Convert Vacuum Energy into Detectable Matter?
Stephen Hawking's groundbreaking theory explains how quantum fluctuations near a black hole's event horizon can result in the creation of real particles. We'll dive into the fascinating world of black hole thermodynamics and explore how this process leads to the gradual evaporation of black holes. Learn about the information paradox and its implications for our understanding of quantum mechanics and gravity.

How did inflationary cosmology turn 'nothing' into a universe brimming with galaxies and stars?
The theory of cosmic inflation provides a compelling explanation for how the universe rapidly expanded in its earliest moments. We'll explore how this process amplified quantum fluctuations into the large-scale structures we see today. Discover how inflation solves key problems in cosmology and why it's considered a cornerstone of modern Big Bang theory.

How does the Casimir Effect manipulate 'nothing' to produce measurable forces?
The Casimir effect, arising from the difference in quantum vacuum fluctuations between two conducting plates, demonstrates that 'empty space' is far from empty. We'll explore the experimental evidence for this effect and its potential applications in nanotechnology. Learn how this phenomenon challenges our understanding of vacuum energy and its implications for the cosmological constant problem.

Can the concept of Zero-Point Energy redefine our understanding of a true vacuum?
Zero-point energy, the lowest possible energy that a quantum mechanical system may have, has profound implications for our understanding of the vacuum. We'll explore the theoretical predictions of vacuum energy density and the stark contrast with observational evidence, known as the vacuum catastrophe. Discover the potential applications and limitations of harnessing zero-point energy.

How Vacuum Decay Would Destroy The Universe?
Finally, we'll delve into the unsettling possibility of vacuum decay, a process that could rewrite the laws of physics as we know them. Learn about false vacuums, quantum tunneling, and how a bubble of true vacuum could expand at the speed of light, obliterating everything in its path. We'll discuss the likelihood of this event occurring and its implications for the long-term fate of the universe.

Einstein's Quantum Riddle | Full Documentary | NOVA | PBS

1 Views · 8 months ago

Join scientists as they grab light from across the universe to prove quantum entanglement is real.

#NOVAPBS Official Website: https://to.pbs.org/3vqiMpg

Einstein called it “spooky action at a distance,” but today quantum entanglement is poised to revolutionize technology from computers to cryptography. Physicists have gradually become convinced that the phenomenon—two subatomic particles that mirror changes in each other instantaneously over any distance—is real. But a few doubts remain. NOVA follows a ground-breaking experiment in the Canary Islands to use quasars at opposite ends of the universe to once and for all settle remaining questions.

(Premiered January 9, 2019)

03:52 Is Quantum Entanglement Real?: Canary Islands Experiment
08:10 The Beginnings of Quantum Mechanics

Gravitational Force is not a force #shorts #science #physics #experiment #education

1 Views · 8 months ago

All bodies in this universe is attract each other by gravitational force, atleast we all have studied till date. The universe is like space-time sheet which can be deflated by the weight of body and the small bodies fall into the pit formed by heavy bodies. Free fall of bodies are actually happen due to this phenomenon which proves that gravitational force is not a force. All bodies actually moving in their respective paths and they meet where they cross their path. We only see things in one,two or three dimension with our naked eyes and can't see other remaining dimension. #shorts #science #physics #education #spacetime @CONCEPTUALGURUJI

Why do we see rainbows in soap bubbles? What makes an oil slick so oddly beautiful? Iridescent colors, which transform depending on the angle you look at them, are all over nature. How does physics make these shifting rainbows? We’re going to find out with the help of the National Museum of Natural History's most spectacular specimens – from bird feathers and beetle wings to fossils and gemstones.
