After some serious number crunching, a researcher says that he has come up with a mathematical model for a viable time machine: a Traversable Acausal Retrograde Domain in Space-time (TARDIS). He ...

Time travel is deterministic and locally free, a paper says—resolving an age-old paradox. This follows research observing that the present is not changed by a time-traveling qubit. It’s still not very ...

Schools are starting to switch from learning math through memorization to learning it by problem-solving, focusing on understanding concepts. Ashwaubenon added class time to math and ELA in middle ...

The hour, minute and second hands of this clock are all the same length and move smoothly in a circle. The dial contains hour and minute markers, but the numbers are missing. Therefore, it’s ...

Anyone can now download StarFall meteor detection software designed by Utah State University's Space Dynamics Laboratory. Meteors rarely cause terrestrial damage — but accurate and timely detection of ...

The US Education Department, which the Trump administration is actively attempting to dismantle, has released the latest math and reading test scores for American high-school seniors — and they’re an ...

The StarFall software enables users to detect bolides, or fireballs, in the sky in near real-time. Bolides are a type of bright meteor which explode as they enter Earth's atmosphere. While many bolide ...

The original version of this story appeared in Quanta Magazine. At the turn of the 20th century, the renowned mathematician David Hilbert had a grand ambition to bring a more rigorous, mathematical ...

Find one million consecutive positive numbers, none of which are prime. Ancient math tells us that prime numbers (2, 3, 5, 7, 11, ...,), which have no factors except for 1 and themselves, go on ...
