Einstein Meets Lemaître | Mind Matters

Einstein Meets Lemaître | Mind Matters

Published by skeptic

Editor’s note: Discovery Institute Press is delighted to announce the publication of The Big Bang Revolutionaries: The Untold Story of Three Scientists Who Reenchanted Cosmology, by Jean-Pierre Luminet. The book has received rave reviews including from three Nobel Prize winners. The following is an excerpt from Chapter 12. Georges Lemaître’s work is notable for providing the first interpretation of cosmological redshifts as a natural effect of the expansion of the universe within the framework of general relativity, instead of attributing it to the real motion of galaxies. As it is given in equation 23 — R′/R = v/cr — space is constantly expanding and consequently increases the apparent separations between galaxies. This idea would prove to be one of the most profound discoveries of our time. The proportional relation between the recession velocity v and the distance r is an approximation valid at not too large distances which can be used, he writes, “within the limits of the visible spectrum.” Then, using the available astronomical data, Lemaître calculates the relation in equation 24, with a factor 625 or 575 km/s/Mpc (which means that galaxies …

Turning scientific constraints into breakthroughs: Einstein, Heisenberg and Gödel

Turning scientific constraints into breakthroughs: Einstein, Heisenberg and Gödel

Published by skeptic

Astrophysicist Janna Levin discusses three examples of constraints in science, and how they ultimately led to massive breakthroughs in physics and mathematics.  Abiding by the speed of light caused Albert Einstein to begin his pursuit into the theory of relativity, Heisenberg’s uncertainty principle planted the seed for quantum mechanics, and Kurt Gödel’s incompleteness theorem led directly to the invention of computers and artificial intelligence.  We often think of constraints as impenetrable barriers that cannot be broken. However, these very constraints have the potential to inspire new ways of thinking and revolutionize the world as we know it. Janna Levin: I became interested in this phenomenon of constraints inspiring creative outbursts. And if you look at the last century, there were three really profound examples of that.  I would say, the earliest that I found incredibly interesting, was the limit of the speed of light, leading Einstein to the theory of relativity. Where a lot of other scientists wanted to remove the limit; they wanted to say, “There is no limit to the speed of light. That …

The true reason why Einstein was history’s greatest physicist

The true reason why Einstein was history’s greatest physicist

Published by skeptic

Although many people struggle to name even one living scientist, practically everyone around the world knows who Einstein was. Perhaps the most famous person of the 20th century, Einstein revolutionized the sciences of physics and astronomy, making important contributions that taught us: the speed of light is the same for everyone, that energy and mass are equivalent, and related by the equation E = mc², that light and electrons are both quantized into discrete “packets” of energy, and that space and time are not absolute and objective, among many other discoveries that are still relevant today. Einstein’s work continues to endure on a number of other fronts as well, including on paradoxes in quantum entanglement (the EPR paradox), on connecting two well-separated points in spacetime through wormholes (Einstein-Rosen bridges), and in describing the statistics of integer-spin particles (Bose-Einstein statistics). That would have been enough for a remarkable career and a place among the all-time greats in physics. But the crown jewel of Einstein’s achievements was his revolutionary new theory of gravity — general relativity — …

Einstein on the run: how the world’s greatest scientist hid from Nazis in a Norfolk hut | Albert Einstein

Einstein on the run: how the world’s greatest scientist hid from Nazis in a Norfolk hut | Albert Einstein

Published by skeptic

In September 1933, a humble wooden hut on a secluded Norfolk heath became the improbable location of one of the most important hideouts in history. Nearly a century later, the rarely told story of the three weeks Albert Einstein spent holed up in a heathland bothy, on the run from Nazi assassins, has been turned into an unusual type of docudrama. Using Einstein’s own words, Netflix’s Einstein and the Bomb will shine a light on how the celebrated German Jewish scientist’s brief sojourn on Roughton Heath came at a crossroads in his life – and, consequently, changed the course of history. “It was only as we looked closer that we realised quite what a seismic moment in his life it was,” said the screenwriter Philip Ralph, a “verbatim specialist” who used only Einstein’s actual speeches, letters and interviews to script the theoretical physicist’s dialogue.

Einstein may be wrong about how mirrors travelling at light speed work

Published by skeptic

How does a mirror travelling at light speed behave? We may now know Imagine Photographer/Getty Images Over a century ago, Albert Einstein found a paradox during a thought experiment involving mirrors moving at the speed of light. Now, a new set of calculations may have unravelled it. “If you search the internet for ‘what would you see in a mirror moving at the speed of light?’ you will find intense discussions on physics-related forums. Curiously enough, none of the proposed answers are correct,” says Sergei Bulanov at the ELI Beamlines Facility in the… Source link

Einstein wasn’t a lone agent. Here’s why that matters.

Published by skeptic

Science writer George Musser discusses the essence and nature of science, emphasizing its purpose as a means to understand and create a consistent view of reality. While we often imagine science geniuses such as Einstein as lone rangers in their field, scientists continuously share and refine ideas among colleagues, underlining the importance of friendships and trust in discoveries. Such relationships enable the initial testing of concepts in a supportive environment before they face the broader, often critical scientific community. Citing Einstein’s interactions with Niels Bohr, Musser illustrates how even foundational principles, like the Heisenberg Uncertainty Principle, were continually probed and questioned — not out of disbelief, but out of a quest for deeper understanding. However, not all scientific dialogues result in consensus. One study suggested that the most innovative scientists often remain firm in their views, hinting that a certain degree of stubbornness might be beneficial for scientific progress. In essence, the rigorous, collaborative, and sometimes contentious interactions among scientists are fundamental to advancing knowledge. George Musser: What is the purpose of science? It is …
