Someone at work sent me this algebra puzzle, which I think came from The Times newspaper:

Solve 9ˣ+15ˣ=25ˣ.

(Put a CW on solutions in replies, please!)

Have you seen it before? Did you see it in The Times?

too much time without stargazing 🤩 short observation of the moon quarter with the sun rise on Rupes Recta , the shadow of on its rings , but I couldn't see before clouds cover the sky ...

M11-the Wild Duck cluster- is a rich open cluster of stars about 6000ly away in the constellation of Scutum. An easy find in a pair of binoculars, it's always worth a look in the summer sky.

Thanks #Matlab for not using common keyboard shortcuts but using them in #Simulink.

Copy? Let’s use alt+w!
Paste? How about ctrl+y?

Why?

Once you get used to them they won’t work with Simulink. Obviously. :thisisfine:

My girlfriend just installed #Matlab for Uni. Why on earth does it take up 40gb?!

Around this time of the #LunarCycle, the #Moon is very close to the position of the #Sun in the sky and so to get a picture of it, you either have to be up just before dawn for the #OldMoon and just after dusk for the #NewMoon. The actual new Moon was yesterday but this evening, I managed to capture this thin sliver of a #WaxingCrescent. Of course it’s very dim at present and so I had to use a #tripod.

très fin croissant de Lune visible ce soir très bas sur l'horizon ouest et qui marque le début du Ramadan (1/5eme sec 400ISO 300mm F/5.6 et 1/125eme 1600ISO 135mm F/4). Demain soir même heure le croissant sera bien plus haut et vous pourrez apprécier la lumière cendrée de la lune (partie du disque non éclairée par le soleil, mais éclairée par un "clair de Terre") ...
