Merry Grav-mass!

On December 25, Isaac Newton's birthday, we celebrate the existence of comprehensible physical laws. Remember, Gravitation is a well-established scientific theory, but Intelligent Falling is just religion pretending to be science.

One way to celebrate Grav-mass is to decorate a tree with apples and other fruits. Glue them or attach them, but not too well! The idea is that occasionally a fruit should fall. Put them on the tree no more than 2 feet up, so that they won't get damaged or hurt anybody when they fall. Investigating and perfecting the methods for doing this is a great way expose a child to the process of scientifically studying the behavior of the physical world.

Another way to celebrate Grav-mass, in a group, is by telling each other about scientific knowledge and understanding, or discussing what kind of experiment could answer an unresolved question about the world.

We have one Grav-mass carol, We Three Laws. If you know of any others, please tell me about them: rms at gnu dot org. Other songs about science are also suitable to play or sing on Grav-mass;

The Ten Days of Newton.

In Spanish: ¡Feliz Gravidad!
In Bahasa Indonesia: Selamat Hari Gayaberat.
In Chinese, 牛诞节快乐！.
In Greek, Kαλά Bαρυτούγεννα (Kala Varitouyenna).
In Polish, Grawiazdka.
In Italian, Buon Gravitale.
In German, Frohe Schwernachten.

I think the idea of Grav-mass was conceived by science fiction writer James Hogan.

Here is a video Grav-mass greeting.
