Albert Einstein’s general theory of relativity predicts that a rotating mass like the Earth pulls the fabric of space and time around with it in a perpetual swirl. This phenomenon is known as frame ...

Physicists have debated which way a submerged sprinkler sucking in water would spin. Careful experiments provide an answer.

A diamagnetic substance is slightly repelled by magnetic fields. With a strong enough magnet, the diamagnetic force can ...

Quirky backyard sprinklers helped scientists solve a decades-old mystery about how flowing water makes objects spin.

Researchers at New York University’s Courant Institute conducted a series of experiments with different silly sprinkler designs to find the answer to a longstanding problem in fluid dynamics, ...

A team of mathematicians used whimsical "silly sprinklers" to solve a physics mystery that has puzzled scientists for decades. Their experiments showed that the rotation of both normal and reverse ...

A deep technical guide to how modern AI really works—from neural networks and transformers to RAG, embeddings, reasoning ...

Scientists have pinned down why a sprinkler spins when it sucks in water instead of spraying it out — a problem that stumped ...

July 21, 2026 Scientists have created a programmable optical chip that can slow light on demand, giving engineers far greater control over how optical signals propagate through a circuit. The ...

Earlier this year, the Lacks estate settled a lawsuit regarding a company’s profiting off of HeLa cells. The case serves as a reminder of the importance of proper ethics in human research.

A fancy name for a row vector is a "covector" or linear form, and the fancy version of the relationship between row and column vectors is the Riesz representation theorem, but until you get to ...

Change to the branch that you want to improve (usually develop) and create a new branch hg branch <branchName> where <branchname> is an easily identifiable name that makes the purpose of the branch ...
