How a race between two scientists to liquefy gases led them near to absolute zero - the coldest temperature possible. Physics - Energy And Radioactivity - Learning Points. Absolute zero occurs at -273.15 degrees Celsius. Absolute zero is...

Lasers are usually associated with heat. But scientists have instead used them to reach the coldest temperature ever recorded. Could they reach absolute zero? Physics - Energy And Radioactivity - Learning Points. Absolute zero is...

How a unique but simple experiment in the 19th century gave a new insight into the behaviour of sound waves. Physics - Waves - Learning Points. The Doppler Effect is when the pitch of a sound seems to change as it moves past. The...

Learn about Marie Curie, the extraordinary woman scientist who won multiple Nobel Peace Prizes and helped develop early x-ray technology.

Learn about the German genius, Albert Einstein, from his early days at the patent office to his final days at Princeton, NJ.

In the 1980 s, the United States Air Force pioneered a Big Idea. It was a new method of navigation via satellite, predicted to have significant benefits for civilian, as well as military transportation. It was then called NAVSTAR, but is...

Returning again to analytic philosophy, we arrive at the Vienna Circle and the logical positivists. There were many important members of this group, and Ludwig Wittgenstein was a frequent collaborator. Let's see what they were all about!

How random are things, really? Well, at the tiny level of photons, randomness might be key to their existence. Einstein could not accept this and famously held the paraphrased opinion that, ‘God does not play dice with the universe’. In...

This video explores the Ulysses spacecraft's mission to study the Sun's polar regions, providing valuable insights into the nature of our nearest star. By observing from above the Earth's atmosphere, Ulysses has revealed a clearer...

In this video, we explore the fascinating world of solar observations and the mission of the Ulysses spacecraft. We learn about the immense complexity of the Sun and how it affects our planet. The video highlights the importance of...

The video discusses two separate topics: the deteriorating state of the Titanic wreck and the search for evidence of antimatter. It highlights the alarming decay of the Titanic wreck, which is on the verge of collapsing, and the efforts...

Nobel Laureate Antony Leggett, University of Illinois, describes how the field of foundations of quantum theory changed from being a "fringe activity" to one squarely within the academic mainstream thanks to the work of a few "mavericks".

Princeton historian of science Michael Gordin reflects upon the internal mechanisms behind the publication of Immanuel Velikovsky’s notorious book Worlds In Collision in 1950, explaining how peer review was very different then than it is...

Quantum physicist Artur Ekert (Oxford and NUS) describes how foundational issues of quantum theory were long ignored by the physics community.

Duke neuroscientist Miguel Nicolelis explains his view that the scientific tradition that many biologists inherited from physics of trying to understand the brain by focusing on the neuron as the basic building block, isn’t actually the...

Nobel Laureate in Physics Anthony Leggett (Illinois) describes the so-called Anthropic Principle that some invoke to answer the "fine tuning problem" of cosmology.

Astrophysicist Scott Tremaine, Institute for Advanced Study, describes how our understanding of black holes has evolved from a time when Einstein didn't actually believe they existed to our present view that so-called "supermassive"...

How do you test quantum mechanics with ancient stars? A new experiment aims to close loopholes to the iconic "Quantum Bell Test", with new results published in Feb. 2017!

From Newton's laws to E=mc2, we think we have uncovered the secrets of the universe. But some claim these laws evolve and others point to their human and cultural origins. Might eternal natural laws be human hubris? Or is the mind of God...

Dark matter is a scientific mystery. We can't see or touch it. But physicists like Dan McKinsey theorize it must exist because without it, the universe would look quite different. With support from the National Science Foundation,...
