Salvare un link con Google
Ok, cerco di capire. Se voglio salvare un link per futura lettura utilizzando un servizio Google, lo posso fare addirittura in tre modi differenti:

- Google Keep: si con app mobile condividendo il link, sia con la nuova estensione (https://goo.gl/kdYqbG).

- Salva in Inbox: nuova funzionalità di Inbox attivabile sia da app mobile, sempre condividendo il link in questione, sia da relativa estensione (https://goo.gl/aLTWYK). In questo caso il link salvato diventa anche un promemoria che poi vedo quotidianamente su Calendar.

- Save to Google: estensione per Chrome specifica per questo utilizzo (https://goo.gl/reBx5W), che rimanda poi al relativo, nuovo e ancora disponibile a singhiozzo servizio (https://goo.gl/abRZ04).

Ora, se quest'ultimo servizio facesse da ponte per questa funzionalità e inglobasse i diversi link che salvo nei diversi modi non sarebbe male! Perchè per adesso mi piace la possibilità di Keep di aggiungere al link una nota, ma Inbox è più flessibile, ma ad entrambi manca una pagina di riferimento che mi permetta di organizzare i link salvati. Insomma i tre servizi dovrebbero proprio diventare uno.
Che ne dite?

Paramagnetism of Liquid Oxygen

Watch this video from the Royal Institution>>
https://www.youtube.com/watch?v=rz57PJToGEs

You can see that the liquid oxygen is prepared by passing oxygen gas through a copper coil immersed in a beaker of liquid nitrogen. The oxygen has a higher boiling point than nitrogen meaning that it condenses in the coil. 

Then the paramagnetic properties of liquid oxygen are demonstrated  by pouring oxygen between two poles of a large magnet. 

The reason liquid oxygen holds magnetic properties is because of its unique arrangement of electrons.

In liquid oxygen, each unpaired electron acts almost like a small magnet. Away from the presence of a permanent magnet, these mini-poles are oriented in random directions, but they actually align themselves under the influence of a magnetic field. This causes the entire glob of liquid oxygen to behave as a small magnet. This is why the oxygen stays in place between the two poles of this magnet.

The reason gaseous oxygen doesn’t readily exhibit these same properties is because it has too much kinetic energy. That means it’s harder to align the mini-poles that so easily align in liquid oxygen.

This experiment is a great example of the counter-intuitive nature of science. In our every day experience, oxygen is invisible and has seemingly no significance to us. When condensed into a liquid, however, not only does it display a hint of blue, but also astonishing characteristics like paramagnetism.

Michael Faraday discovered that the magnetic properties of gases depended on the temperature of the gases as well as the gaseous medium in which he conducted his experiments. He first observed that oxygen behaved magnetically, rather than diamagnetically, at the Royal Institution in 1847

E finalmente abbiamo un prototipo di macchina con sterzo funzionante! Grazie al servomotore accoppiato perpendicolarmente al meccanismo assiale di sterzo :)

Il film mi è piaciuto parecchio. Inoltre hanno fatto un'operazione di reboot come, personalmente, non avevo mai visto. Pollice decisamente su per me.
