Première loi de Newton ou principe d’inertie

Première loi de Newton ou principe d’inertie // Newton’s first law or principle of inertia

Today’s prompt is “law”, loi.

The Newton’s first law of motion says:

Tout corps persévère dans l’état de repos ou de mouvement uniforme en ligne droite dans lequel il se trouve, à moins que quelque force n’agisse sur lui, et ne le contraigne à changer d’état.
All bodies persevere in the state of rest or uniform movement in a straight line in which they find themselves, unless some force acts on them, and compels them to change their state.
The “law of inertia” is used so much to explain all sort of (non)occurrences, not necessarily physical ones, that it almost lost its original meaning. I, for one, completely forgot about the “movement in straight line” part of it.

In quarantine news: Canaries are moving to phase 1 of de-quarantining on Monday. I am still not quite sure how it will work, but surely there will be more freedom to move and do stuff. So... I will draw a last pic-a-day on Monday and the take a well-deserved break.

Le gagnant prend la première vague

Le gagnant prend la première vague // The winner takes the first wave

Today’s prompt is “winner”, gagnant.

So here is the cat, winning the first wave of the morning on Las Canteras. The slot allowed for non-professional sports, including aquatic, is currently from 6 am to 10 am, the evening slot is shorter and has almost no daylight. Surfers (all sportsmen, actually) are not allowed to take a motorised vehicle to get to the place where they do their thing, everybody has to get there under their own steam. So many of them are pretty puffed when they finally arrive.

Today is the third day of allowed physical exercise and things are going ok, except it’s Monday and some people, in theory, are going to work. So, being generous, you can assume the electric scooters are back on bicycle paths for a good reason (though I strongly suspect not all of them are). Regulations for those are still lacking, and they are public menace at the best of times. Right now, when everybody is trying to walk, run and cycle within the same allowed slot, they are downright danger.

Premier principe de la thermodynamique

Le premier principe de la thermodynamique: <...> il y a conservation de l’énergie //
The first law of thermodynamics: <...> there exists conservation of energy

Today’s prompt is “physics”, physique.

The cat confirms it: conservation of energy exists. He also thinks it makes good sense to conserve the old energy there. In fact, he is an absolute expert on conservation of energy. Look at him there in his hammock, conserving it with all his might. He was reading a book about himself, but then the sudden urge to conserve overwhelmed him.

In quarantine news: today it looks like people are adapting to the new schedules, there was no such mad rush to open spaces as yesterday morning. Of course, yesterday towards the evening all the papers were full of reports of various violations of regulations, photos of seemingly crowded streets and parks, the number of fines given, etc., etc..., but I rather think it went ok, more or less.
