wired.com Stephanie Pearson 2025-07-19 13:00:00

Love them or hate them, electric bikes are here to stay. Between 2019 and 2023, electric bikes represented 63 percent of the growth in dollar sales of all bicycles.

Some electric bike customers haven’t been on two wheels since they rode a Schwinn Stingray with a banana seat; others are lifelong cyclists who want a little extra oomph to flatten the hills

Earlier this year I saw a Tech Ingredients episode where a laser gimbal automatically tracks drones and shoots them down. I was fascinated by their motion control mechanism, specially the usage of a PI Controller, a high-frequency clock Teensy microcontroller, and their integration with custom hardware and a machine vision powered tracker. Soon after I was researching the underlying electronics and how to experiment upon their concepts. The most obvious microcontroller to drive these would be a

The tech behind Rivian’s 2026 Quad Motor truck and SUV — and that kick turn

As Rivian starts accepting orders for its 2026 Quad Motor pickup truck and SUV, customers may initially be enticed by the power and tricks the four motors in these rebooted EVs can unleash. After all, four motors delivering a combined 1,025 horsepower and 1,198 pound-feet of torque — and the ability to accelerate from a standstill to 60 miles per hour in less than 2.5 seconds — is hard to ignore.

Rivian provided flights from Albany, New York, to Reno, Nevada, and accommodation so Ars could drive the quad-motor R1s. Ars does not accept paid editorial content. It's getting harder to find hyperboles to describe the performance of modern EVs. Horsepower figures measured in four digits and acceleration figures clocking in well under three seconds aren't exactly de rigueur, but they're well short of rare these days.

Previously: Fibrations and Cofibrations. In topology, we say that two shapes are the same if there is a homeomorphism– an invertible continuous map– between them. Continuity means that nothing is broken and nothing is glued together. This is how we can turn a coffe cup into a torus. A homeomorphism, however, won’t let us shrink a torus to a circle. So if we are only interested in how many holes the shapes have, we have to relax our notion of equivalence. Let’s go back to the definition of home
