Synthetic biology reinvents development

Posted by in categories: bioengineering, biological, mathematics, physics

Richard Feynman, one of the most respected physicists of the twentieth century, said “What I cannot create, I do not understand.” Not surprisingly, many physicists and mathematicians have observed fundamental biological processes with the aim of precisely identifying the minimum ingredients that could generate them. One such example are the patterns of nature observed by Alan Turing. The brilliant English mathematician demonstrated in 1952 that it was possible to explain how a completely homogeneous tissue could be used to create a complex embryo, and he did so using one of the simplest, most elegant mathematical models ever written. One of the results of such models is that the symmetry shown by a cell or a tissue can break under a set of conditions.

A Physicist Has Worked Out The Math That Makes ‘Paradox-Free’ Time Travel Plausible

Posted by in categories: mathematics, physics, space, time travel

No one has yet managed to travel through time – at least to our knowledge – but the question of whether or not such a feat would be theoretically possible continues to fascinate scientists.

As movies such as The Terminator, Donnie Darko, Back to the Future and many others show, moving around in time creates a lot of problems for the fundamental rules of the Universe: if you go back in time and stop your parents from meeting, for instance, how can you possibly exist in order to go back in time in the first place?

It’s a monumental head-scratcher known as the ‘grandfather paradox’, but in September last year a physics student Germain Tobar, from the University of Queensland in Australia, said he has worked out how to “square the numbers” to make time travel viable without the paradoxes.

Ten “Keys to Reality” From Nobel Laureate Frank Wilczek – Understanding Ourselves and Our Place in the Universe

Posted by in category: mathematics

To understand ourselves and our place in the universe, “we should have humility but also self-respect,” the physicist writes in a new book.

In the spring of 1970, colleges across the country erupted with student protests in response to the Vietnam War and the National Guard’s shooting of student demonstrators at Kent State University. At the University of Chicago, where Frank Wilczek was an undergraduate, regularly scheduled classes were “improvised and semivoluntary” amid the turmoil, as he recalls.

It was during this turbulent time that Wilczek found unexpected comfort, and a new understanding of the world, in mathematics. He had decided to sit in on a class by physics professor Peter Freund, who, with a zeal “bordering on rapture,” led students through mathematical theories of symmetry and ways in which these theories can predict behaviors in the physical world.

A Theoretical Physicist Grapples With the Math of Consciousness

Posted by in categories: mathematics, neuroscience

Even for the brain of a worm, the best theory on offer would, she says, take several billion years to calculate. That can’t be the right answer.

2020’s Biggest Breakthroughs in Math and Computer Science

Posted by in categories: computing, mathematics, particle physics, quantum physics, science

For mathematicians and computer scientists, 2020 was full of discipline-spanning discoveries and celebrations of creativity. We’d like to take a moment to recognize some of these achievements.

1. A landmark proof simply titled MIP = RE” establishes that quantum computers calculating with entangled qubits can theoretically verify the answers to an enormous set of problems. Along the way, the five computer scientists who authored the proof also answered two other major questions: Tsirelson’s problem in physics, about models of particle entanglement, and a problem in pure mathematics called the Connes embedding conjecture.

Ancient Mayan Math Makes A Come Back In Mexico

Posted by in categories: education, food, mathematics

News Americas, MIAMI, FL, Fri. Mar. 22018: A form of calculation that made the ancient Mayans such a successful race has been rediscovered by academics in Mexico, and is now being taught to the descendants of the long-lost culture.

Mayan math, an ancient mathematical method invented by the Mayans, has made the mathematicians of the long-lost civilization that built Chichen Itza in the jungles of the Yucatan Peninsula some of the most advanced of their time.

Now students in the remote village of Kanxoc are learning the ancient method and doing simple arithmetic with beans, sticks and pasta shells on a simple grid.
