Not only do I get the "shape" of the acceleration curve for the colliding cart, but I also get a maximum acceleration of –6.67 meters per second squared. With that acceleration and the mass of the cart (0.566 kilogram), we get a maximum impact force of 3.73 newtons.This isn't quite the same value I obtained from the force sensor—and that's OK. There are two main reasons why the maximum force is different with this method. First, I've only collected a position point every 1/30th of a second, because my video frame rate was…

The 2018 data shows how much CO2 the energy sector in Mongolia emitted, comparing two calculation methods. One is Mongolia's BUR2 using the bottom-up approach (left) and EDGAR (right). The other is the calculation result from this study using the hybrid approach (center) based on the top-down approach. The green represents CO2 emissions for all of Mongolia, while the red indicates emissions from Ulaanbaatar city. Note that for BUR and top-down data, the…

Typical heart rate monitoring in wearable tech, like smart watches or wireless earbuds, relies at least partially on photoplethysmography (PPG), which uses light pulses to measure blood activity. It works generally well, but it has its limitations. Google scientists wrote in a new research blog spotted by 9to5Google yesterday that they had tried a different approach, called audioplethysmography (APG), that uses ultrasound to measure heart rate. And they did it with off-the-shelf active noise-canceling (ANC) earbuds and a…

This Halloween, when you grab a candy bar, pay attention to the wrapper. In the United States, a "nutrition facts" label has been required for all packaged foods since 1994, giving the serving size and the amount of sugar, protein, fat, and sodium the food contains. But the most interesting bit is the metric for energy, which is listed as "calories." What does energy really mean when it comes to candy?Flavors of EnergyIn physics, the concept of energy helps us keep track of different types of interactions. We say energy…

The term BMI is all over health care. The abbreviation stands for body mass index, a simple number that has evolved into a ubiquitous medical tool for obesity screening. For example, a BMI from 18.5 to 24.9 indicates a “normal” weight status, according to the World Health Organization, while a BMI of 30 or higher signifies obesity, a condition that raises your likelihood of developing type 2 diabetes, cardiovascular disease, various cancers and other illnesses. The metric has become a catchall proxy for body fat…

Twitter will now require users to have an account on the social media platform to view tweets, a move that owner Elon Musk on Friday called a "temporary emergency measure".Users who try to view content on the platform will be asked to sign up for an account or log into an existing account to see their favourite tweets."We were getting data pillaged so much that it was degrading service for normal users!" Musk said in a tweet.He added that hundreds of organizations or more were scraping Twitter data "extremely…

Amid the buzz around weight loss drugs and rising rates of obesity worldwide, many health care professionals are questioning one of the key measures that has long been used to define obesity.On June 14, 2023, the American Medical Association adopted a new policy, calling on doctors to deemphasize the role of body mass index, or BMI, in clinical practice.The statement by the AMA, the nation's largest association representing physicians, signals a significant shift in how clinicians regard BMI as a measure of general…

I use the Apple Watch for health and fitness tracking purposes, especially with my newfound passion for running, which made me turn to ChatGPT for better running shoe recommendations. I had particular conditions for the running shoes I wanted, with an emphasis on comfort and protection against certain injuries. The reason I mention running is simple: I have high expectations for the Apple Watch of the future handling my health data during those runs as well as regular activities. The device will hopefully…
