For every kilogram of matter that we can see—from the computer on your desk to distant stars and galaxies—there are 5 kilograms of invisible matter that suffuse our surroundings. This “dark matter” is a mysterious entity that evades all forms of direct observation yet makes its presence felt through its invisible pull on visible objects.
Vortices are a common physical phenomenon. You find them in the structure of galaxies, tornadoes and hurricanes, as well as in a cup of tea, or water as it drains from the bathtub.
Actually, nothing is wrong with it if you are a computer science major. It’s just that it has no place in the philosophy department.
From the point of anyone wanting to work in natural language, symbolic logic has all of the vices of mathematics and none of its virtues. That is, it is obscure to the point of incomprehensibility (given the weak neurons of this English major at any rate), and it leads to no useful outcome in the domain of human affairs. This would not be so bad were it not for all those philosophy major curricula that ask freshmen to take a course in it as their “introduction” to philosophy. For anyone looking to explore the meaning of life, this is a complete turnoff.
What were the philosophy mavens thinking?
Neuralink is onboarding patients in the UK in preparation for potential clinical trials amid a Brain-Computer Interface (BCI) boom.
It seems like over the past few years, Quantum is being talked about more and more. We’re hearing words like qubits, entanglement, super position, and quantum computing. But what does that mean … and is quantum science really that big of a deal? Yeah, it is.
It’s because Quantum science has the potential to revolutionize our world. From processing data to predicting weather, to picking stocks or even discovering new medical drugs. Quantum, specifically quantum computers, could solve countless problems.
Dr. Heather Masson-Forsythe, an AAAS Science \& Technology Fellow in NSF’s Directorate for Computer and Information Science and Engineering, hosts this future-forward episode.
Featured guests include (in order of appearance):
Dr. Spiros Michalakis, the manager of outreach and a staff researcher at Caltech’s Institute for Quantum Information and Matter, an NSF Physics Frontiers Center.
Dolev Bluvstein, a doctoral student at Harvard University, working in the Lukin Group at the Quantum Optics Laboratory.
Dr. Scott Aaronson, Schlumberger Chair of Computer Science at The University of Texas at Austin and director of its Quantum Information Center.
In an interview Dr Stephanie Simmons, Chief Quantum Officer of Photonic, explains the need to scale quantum computers and their approach to tackling this challenge to pave the way for reliable, large-scale quantum computing.
For quantum computers to move from laboratory to commercialization, these devices will need to scale to millions of qubits.
Scaling quantum computers is critical to unlocking exponential speed-ups to help solve some of the world’s biggest problems and unlock its greatest opportunities, said Stephanie Simmons, CQO of Photonic, a company focused on using its photonically linked spin qubits in silicon to build a scalable, fault-tolerant and distributed quantum system.
Calcium oxide is a cheap, chalky chemical compound commonly used in the manufacturing of cement, plaster, paper, and steel. But the material may soon have a more high-tech application.
UChicago Pritzker School of Molecular Engineering researchers and their collaborator in Sweden have used theoretical and computational approaches to discover how tiny, lone atoms of bismuth embedded within solid calcium oxide can act as qubits — the building blocks of quantum computers and quantum communication devices.
These qubits are described in Nature Communications (“Discovery of atomic clock-like spin defects in simple oxides from first principles”).
