Almost always, it simply splits back into two protons, but on very rare occasions, a stable deuteron hydrogen-2 is produced. Without the power of nuclear fusion, which is made possible through quantum mechanics, none of what we recognize as 'solar output' would be possible. Rather than a world and a sky alight with the nuclear fires burning across the cosmos, our Universe would be desolate and frozen, with the vast majority of stars and solar systems unlit by anything other than a cold, rare, distant starlight. Yet with this randomness, we win the cosmic lottery all the time, to the continuous tune of hundreds of Yottawatts of power.
Thanks to the fundamental quantum uncertainty inherent in the Universe, we've achieved a chance at existence. It requires the wave nature of quantum mechanics to make it possible, proving that Einstein's famous statement, that "God does not play dice with the Universe," was false. All the way up until his death in the s, Einstein refused to believe, as he called it, that "God played dice" with the Universe.

Ten years later, Einstein would complete the transformation of our understanding of space and time with the formulation of his general theory of relativity, in which the force of gravity is replaced by curved spacetime.
O ver time, Einstein evolved a much more realist position. And, although he wanted no part of religion, the belief in God that he had carried with him from his brief flirtation with Judaism became the foundation on which he constructed his philosophy. For this, he was considered a dangerous heretic , and was excommunicated from the Jewish community in Amsterdam.
He is also firmly determinist. The special and general theories of relativity provided a radical new way of conceiving of space and time and their active interactions with matter and energy. But the new theory of quantum mechanics, which Einstein had also helped to found in , was telling a different story.
Quantum mechanics is about interactions involving matter and radiation, at the scale of atoms and molecules, set against a passive background of space and time. In essence, Bohr and Heisenberg argued that science had finally caught up with the conceptual problems involved in the description of reality that philosophers had been warning of for centuries. There is only an abstract quantum physical description.
It is wrong to think that the task of physics is to find out how nature is. Physics concerns what we can say about nature.
The stage was thus set for one of the most remarkable debates in the entire history of science, as Bohr and Einstein went head-to-head on the interpretation of quantum mechanics. It was a clash of two philosophies, two conflicting sets of metaphysical preconceptions about the nature of reality and what we might expect from a scientific representation of this.
The debate began in , and although the protagonists are no longer with us, the debate is still very much alive. Massimo Pigliucci.

Well, it turns out in the late s when Einstein had this breakthrough or this idea that's when quantum mechanics was coming in, this idea of the ultra small, electrons, things like that.
And they seemed to move around not in the clear beautiful ways that Einstein wanted but there was randomness and chance and probability and Einstein thought okay that's the limits of our technical abilities, our observations only see this fuzziness but if we have better tools we'll be able to see things more exactly. Einstein thought that things like uncertainty were just a temporary stage in mankind's development, but the physicist said no the evidence is really clear.
And Einstein said I was burnt once before with that lambda and the expansion of the universe, I'm not going to be burned again. So he dug in, he doubled up and as time went on the evidence for quantum mechanics, for this randomness and probability on the ultra small that evidence became stronger and stronger, but Einstein was stuck. He couldn't let it go. He just thought if I had held at my confidence for ten years before I would have been okay. Well, maybe it might be 20 years, maybe it might be beyond my lifetime but I'm sure Einstein thought I'm sure that the universe can't be disordered.
But for tops as small as atoms, the discrete nature of spin is very important. Because this unit is very small, one does not notice that a normal top really slows down in a rapid sequence of discrete steps, rather than as a continuous process. He seemed to have felt that the uncertainty was only provisional: but that there was an underlying reality, in which particles would have well defined positions and speeds, and would evolve according to deterministic laws, in the spirit of Laplace. This is summed up in the Uncertainty Principle that Heisenberg formulated; the uncertainty in the position of a particle, times the uncertainty in its speed, is always greater than a quantity called Planck's constant, divided by the mass of the particle. Are they all insane to do so? The current physical state of an arrow determines its future physical state. Open Preview See a Problem?
That's why he said, "God does not play dice with the universe," and his good friend Niels Bohr said, " Einstein, stop telling God what to do. David Bodanis is a futurist, business advisor and popular science writer, and when it comes to Einstein, he literally wrote the books — plural. Einstein was one of the greatest scientists in history to date, but he was not above mistakes.
What Einstein meant by 'God does not play dice' more than 25 years' experience writing on topics in science, philosophy and history. .. From Hume, it was a relatively short step to the Austrian physicist Ernst Mach, whose. I, in any case, am convinced He does not play dice with the universe. For example, Quantum Physics is at the heart of transistors (little devices that make our.
His biggest one, according to Bodanis, was being burned by an experience in the s and letting it affect the remainder of his career and work. Einstein famously said that God does not play dice with the universe. He believed that the universe could not be chaotic and random — after all, he had composed an equation for general relativity so simple and concise that it was a thing of succinct, ordered beauty.
That is until he looked at his formula and realized that, if it were true, it predicted that the universe was expanding. Einstein checked this with astronomers, but they said that no, the universe is definitely static — this was the dominant thought circa So Einstein ignored his prediction and had to add a symbol — a lambda — to his equation to account for the static nature of the universe. About ten years later, in , Edwin Hubble and other astronomers uncovered what was to most of the world's experts a new twist: the universe was expanding.
Einstein could have predicted this a decade earlier, and now faced the public embarrassment of retracting part of his equation.
Einstein told a colleague that putting in the lambda was "the greatest blunder of my life. The Glen McLaughlin Collection brings together more than historical examples of 'California as an island'.
