abstract: Something that exists as an idea or thought but not concrete or tangible (touchable) in the real world. Beauty, love and memory are abstractions; cars, trees and water are concrete and tangible. (in publishing) A short summary of a scientific paper, a poster or a scientist’s talk. Abstracts are useful to determine whether delving into the details of the whole scientific paper will yield the information you seek.

There’s an adage attributed to Italian computer scientist, Silvio Micali who once said “cryptographers seldom sleep well.” Micali works on classical cryptography, a field that has been around for thousands of years, relies on ad hoc and often unreliable designs (assumptions) to keep information secure. Micali’s adage refers to this unreliability in assumptions which have been broken repeatedly – be it from ancient Caeser ciphers to modern day cryptography.

Qubits are to quantum computers, just as transistors are to classical computers. However, unlike their classical cousins, qubits are fussier and more sensitive. Qubits are so fragile that any fluctuation to their environment—like an imperceptible change in temperature, magnetic fields, or even a stray cosmic ray—could disrupt the qubit from performing computations.

わたしたちの直感に反する量子力学の法則に従う粒子の集合「量子システム」を研究するのは容易ではない。量子論の土台であるハイゼンベルクの不確定性原理によれば、ある粒子の正確な位置と速度を同時に測定することは不可能だという。それがわからなければ、極めて重要な情報にもかかわらず、何が起きているか理解できない。 例えばある特定の電子の集合を研究するとき、研究者たちはあらゆることを考慮し実験に臨まなくてはならない。その実験は言ってみれば、電子を入れた箱にさまざまな刺激を与え、最終的にどんな様子になったかスナップショットを撮って記録するようなものだ。そうすることで、内部に働いている量子的な動きを見極めようというわけだ。...

For @SN_Explores here's my latest on @Benorlin's recent book "Math for English Majors"- https://t.co/vg8Lfahddu
RT @QuantaMagazine: “It’s a lot of fun for me to see things I thought about some time ago have unexpected new applications. It’s like as a…
Happy to share my latest for @TheSIAMNews! I had fun learning about the #aerodynamics of bird flight for this one! #evolution, #math, #physics, @roskildeuni
The December issue of SIAM News is now live! In this edition, @science_eye overviews a recent study that derived a simple #mathematical equation to succinctly capture the wing flapping frequency a flying #animal must maintain to remain airborne.
