No, You Won’t Be Able to Float on Zero G Day

NewImage

Slate has a good piece de-bunking the myth of Zero G Day which is (supposedly) tomorrow. Sorry to disappoint!

We now have the claim that on Jan. 4, 2014—tomorrow—due to the combined gravity of Jupiter and Pluto, you will be able to jump in the air and float for just a couple of seconds.

It’s hard for me to overstate just how wrong this claim is. After all, the physics is wrong, the claim about Pluto and Jupiter is wrong, and it’s based on a joke made by an astronomer nearly 40 years ago!

If you want the math, then here you go: Even if you add all of the planets together, they pull on you with a force less than 2 percent of that of the Moon! The News Hound article mentions tides, too, but that’s even worse: The combined tidal force from the planets is far less, like 0.005 percent of the Moon’s! Simply put, the planets are just too far away to have any real effect on you. By the way, the Moon orbits the Earth on an ellipse, so its own gravity fluctuates far more than the combined strength of the planets every two weeks.

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
