A pesar de ser un fracaso comercial, representó un adelanto enorme en el uso de dispositivos móviles.
Un día como hoy, hace 34 años, 𝐀𝐩𝐩𝐥𝐞 presentó el Newton.
El 29 de mayo de 1992, durante el Consumer Electronics Show en Chicago, 𝑱𝒐𝒉𝒏 𝑺𝒄𝒖𝒍𝒍𝒆𝒚 mostró al mundo una de las ideas más ambiciosas de Apple: el 𝙉𝙚𝙬𝙩𝙤𝙣, un dispositivo que buscaba poner la computación personal en la palma de la mano.
No era un teléfono, no era una laptop, no era una agenda común. Apple lo llamó Personal Digital Assistant, o PDA.
How is the Moon 🌙 1% of Earth’s 🌏 mass, but its #gravity is 17% of Earth’s ? https://www.astronomy.com/science/how-are-mass-and-gravity-correlated/
The moon's density is 3.34 grams per cubic centimeter (3.34 g/cm3). That is about 60% 📊 of Earth's density https://www.space.com/18135-how-big-is-the-moon.html
🧲❓ The gravitational constant “Big G” has been part of #physics since 1687, but after 17 modern measurements, scientists still can’t agree on its exact value.
At #NIST in #Maryland, physicist Stephan Schlamminger spent a decade trying – even resorting to a sealed-envelope #experiment to avoid subconscious bias. His team’s result slightly disagrees with the accepted value, keeping the #mystery alive.

It's interesting to me how much talk there is about multiverses, entanglement, negative time, picomateials, light-matter (?) particles, consciousness and so on. All great #physics of course. People enjoy the weirdness of it all I guess. And so do I.
However, over the last 2 or 3 years I have became increasingly blown away by #newtonslaws. Yawn yawn. Most pupils have no real concept of these... but me... I have come to realise the shear enormity of #Newton's brain. I mean, seriously... N3 (every force...) is counter intuitive.
And how many people around the globe, over the millennia, got hit on the head by falling fruit and just stopped after cursing, and nursing a bruise?
