How do we weigh Earth without putting it on a scale?

By combining Newton’s laws of gravitation and motion, we can calculate its mass from gravity, Earth's radius, and the gravitational constant.

Earth's mass: 5.972 × 10²⁴ kg.

06/06 — Why do total solar eclipses happen?

When the Moon passes between Earth and the Sun, it can cover the Sun's disk. If their apparent sizes align just right, we get a total solar eclipse. When the Moon appears smaller, a bright ring remains: an annular eclipse.

01/06 — What makes Earth's Moon special?

Of the Solar System's 8 planets, 6 have natural satellites.But Earth's Moon stands out: its mass is about 1/81 of Earth's, and its diameter is about 27% of Earth's.
Why is this ratio so unusual? 🧵

05/06 — Why do the Sun and Moon look similar in size?

The Sun is about 400 times wider than the Moon—but also about 400 times farther from Earth. Their apparent angular diameters are therefore remarkably similar. This geometry makes total solar eclipses possible.

@yuruyurau Hi! I love your sketches.
I’d like to use and explain some of them in educational Creative Coding videos with full credit and links back to your original posts.
Would that be okay?

[Matrix @MatrixChan]

@yuruyurau It's astonishing, like it has a life of its own.

I found a really interesting BEAM tutorial. I didn't expect that people still enjoy making BEAMs.

《這就是Chatgpt》這段文字讓我��起 動畫《地球外少年少女》中的AI“七(seven)"復活的情節，微型機器改造彗星，把彗星變成 神經網絡。

不錯的動畫，背景是近未來，有人工智能、太空、3D打印、心智成長等元素。

發現一個頻道收集了很多老的 BEAM 視頻。

Tierra 是由生態學家Thomas S. Ray ���1990年初開發的。
我第一次了解到這個系統是在大學時候，那時候我對數字生命和廣義生物學感興趣。

我在Chrome 地址欄裡鍵入 https://t.co/dHQD9qEyYy, 給我匹配出來的訪問記錄有 Z-Walker mk III 的網址 ,那是我多年前收藏的一個製作 BEAM Robotics的個人網站。

Tierra aims to study the evolutionary process by the instantiation of evolution in another form, namely in an ecosystem of interacting and competing machine code programs living in the Tierra environment, which emulates a massively parallel computer.
