We need one more thing—how about Newton’s second law? This says the acceleration depends on the net force (Fnet) and the mass (m) of an object. It’s usually written as Fnet = m × a, but we can rearrange it like this: a = Fnet/m. Combining this with our gravitational force, we get something pretty…
United States Secretary of Defense Pete Hegseth directed the Pentagon to designate Anthropic as a “supply-chain risk” on Friday, sending shockwaves through Silicon Valley and leaving many companies scrambling to understand whether they can keep using one of the industry’s most popular AI models. “Effective immediately, no contractor, supplier, or partner that does business with…

The Centers for Disease Control and Prevention reports that more than a quarter of Americans live with disabilities, and 12.2 percent of those have difficulty moving around independently. Disability is the one minority group that anyone could join through illness or injury. And as we age, muscle weakness and other issues can cause difficulties walking…
While the air temperature between fillings varied by up to 12° F, the fuel in our underground tank stayed at a steady 62° F. As a result, we found that after the first few gallons were pumped, the fuel temperature coming out of the nozzle varied very little between morning and afternoon. At both morning…
It’s hard to remember now that people used to be skeptical about electric bikes. Cyclists didn’t want unlicensed motor vehicles in bike lanes; people who didn’t bike found them to be dangerous. Even as more people adopt them to deal with carbon emissions or traffic, ebikes still have many issues. Cheap ones are impossible to…

When the mattress is centered in the bassinet, you should see no gaps between the edge of the mattress and the bassinet walls any larger than one-half inch, or about a finger-width. “A mattress that doesn’t fit tightly may shift…
Blood Pressure Signals continuously analyzes biometric trends that may correlate with cardiovascular strain. A new Nighttime Blood Pressure capability monitors whether blood pressure drops appropriately during sleep. Oura says this metric may reveal cardiovascular risks that daytime readings may miss. You can also add cuff readings to provide additional context. Meanwhile, Nighttime Breathing provides a…
