Who on Earth is exposed to the most ionizing radiation?
Check out Audible: http://bit.ly/AudibleVe
I'm filming a documentary for TV about how Uranium and radioactivity have shaped the modern world. It will be broadcast in mid-2015, details to come. The filming took me to the most radioactive places on Earth (and some places, which surprisingly aren't as radioactive as you'd think). Chernobyl and Fukushima were incredible to see as they present post-apocalyptic landscapes. I also visited nuclear power plants, research reactors, Marie Curie's institute, Einstein's apartment, nuclear medicine areas of hospitals, uranium mines, nuclear bomb sites, and interviewed numerous experts.

Notes about measuring radiation:
Sieverts are a measure of 'effective dose' - that means they measure the biological impact of the energy transferred to tissues from radiation.

Obviously I owe a debt to the fantastic chart made by xkcd, which inspired my visual approach to this video.
https://xkcd.com/radiation/

DOSES MAY VARY
The level of radiation varies widely around the world depending mainly on altitude and geology (excluding nuclear accidents).

Estimates of particular doses also vary. All numbers reported in this video should be taken as order of magnitude only.

The most contentious claim may be that smokers receive the highest dose of ionizing radiation. This is not a whole body dose, but a dose to the lungs as specified in the video. References are here:

「Geminiのチャットがどんどん流れて、先週の話がどこにあるか分からない…」「プロジェクトごとに資料を毎回貼り直すのがしんどい…」
Geminiを使っていて、こんな悩みを抱えていませんか？

2026年4月8日、Geminiにずっと待望だった新機能「ノートブック」が追加されました！
チャットと資料をテーマごとに整理できる自分専用の作業フォルダが作れるようになり、しかも裏側ではNotebookLMと繋がって、同じノートブックをGeminiからもNotebookLMからも使えるようになったんです。

今回はこの「ノートブック」機能の何がすごいのか、基本操作から実践ユースケース3選、そして意外な落とし穴まで全部まとめて解説しました！

📌 この動画で分かること
・Geminiの新機能「ノートブック」の概要（2026/4/8発表）
・「チャットが流れない」体験 — Geminiが作業ツールに進化した理由
・ノートブックの基本操作 — 作成・資料追加・複数チャット・カスタム指示
・裏側のNotebookLM統合 — 同じノートブックを2つの入口から使う仕組み
・実践ユースケース3選（会議準備 / リサーチ＆レポート / プロジェクト管理）
・知らないと危険な共有設定の落とし穴とWeb版のみ対応の注意点

Glass is made of sand, which is a kind of rock. But glass is transparent, and rocks aren’t transparent. What’s up with that? Why is glass clear? And why can I sit on a chair? And why can we touch anything? Today we zoom down to the weird world of electron clouds and quantum touching to find the answers.

Geometry on Khan Academy: We are surrounded by space. And that space contains lots of things. And these things have shapes. In geometry we are concerned with the nature of these shapes, how we define them, and what they teach us about the world at large--from math to architecture to biology to astronomy (and everything in between). Learning geometry is about more than just taking your medicine ("It's good for you!"), it's at the core of everything that exists--including you. Having said all that, some of the specific topics we'll cover include angles, intersecting lines, right triangles, perimeter, area, volume, circles, triangles, quadrilaterals, analytic geometry, and geometric constructions. Wow. That's a lot. To summarize: it's difficult to imagine any area of math that is more widely used than geometry.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

For free. For everyone. Forever. #YouCanLearnAnything

Scientists just found something off the coast of Australia that’s straight out of a nightmare — the fossil of a creature so terrifying it could have gone head-to-head with the mighty Megalodon. Scientists are calling it one of the most fearsome predators to ever rule the ocean… and after seeing what it looked like, you might think twice before diving in again.
