Every Waaagh must begin somewhere. Mine is beginning here. #MiniaturePainting #WH40k #Orks

Miniature of a WH40k orc painted with green-yellow skin and orange armour. View from the front.

Experimenting with a monochromatic colour scheme. As first attempts go, I am quite happy. But it also shows all the skills I need to work on more. #MiniaturePainting #Blue #WH40k

Miniature of a minotaur wielding a rough mace and a gun (possibly from the "Kill Teams" game?) painted only in shades of blue. Except for one red eye.

Fining Meta, X, etc for being exploitative? Of course not!

My very first miniature VS the very same miniature painted almost exactly one year later. I can't call myself a good painter, but at least I improved this year 😃 #MiniaturePainting (mini from #HeroQuest )

Two identical miniatures of an orc with a big hammer (from HeroQuest). The left one is very glossy and the colors are blocky. The right one is painted with more shades.

Painted my first #Bloodbowl team! It was mostly a learning curve on how to paint beards 🤣 #MiniaturePainting

Bloodbowl team of 12 dwarves, painted with white (gray) trousers, purple armour, and copper trims.

Purple is the colour of royalty and of abominable eldritch horrors.

Drop something white!

Pretty happy about this cleric tortle. Especially because I think the whole idea of "volumetric highlights" finally clicked. #MiniaturePainting #Dnd

Cleric turtleman miniature with a large hammer painted with a blue cloak.

Friend plays a bronze dragonborn bard in our #Dnd campaign, so I painted this as a little gift. Have to work more on my silver, but I think the skin turned out ok. #MiniaturePainting

With the arrival or rainbowrk, the colorful brigade of murderous orcs is now complete! #Warhammer #MiniaturePainting #Orc

10 orc miniatures, each painted in a different color.

Jacopo Bertolotti@jacopobertolotti· May 17

Orangiok is now based. One more colorful orc to complete the squad. #Warhammer #MiniaturePainting #Orc

Work in progress on my orange orc. #Warhammer #MiniaturePainting #Orc

Drop some teeth!

Everyone told me white was going to be hard, and now I can 100% confirm. I am unlikely to attempt a white armor for a VERY long time 😓 #Warhammer #MiniaturePainting #Orc

Orc miniature painted with a white armor and bronze trimmings.

1. The true metallic colors by Vallejo are truly good. 2. The wash is super-powerful (i.e. I used too much and the whole thing is way too dark) 3. Never ever be as stupid as me and start putting down grass before the paint on the mini is dry 😓 #Warhammer #MiniaturePainting

Orc miniature painted with a copper armour. In the right hand it holds a big spear with blue reflections.

Somebody made me notice that I needed still a black Powwa Renga, so I pained one. First attempt at black armor, and first real attempt at NMM #Warhammer #MiniaturePainting

Orc miniature painted with a nmm black armor.

With the arrival of the "Fabulous Pink Orc", the "Powwa Renga" orc squad is complete. #MiniaturePainting #Warhammer

5 painted orc miniatures, one in red armour, one in blue, one in green, one in pink, and one in yellow. Placed in a line.

"Why should you be the boss?" "Because I am wearing red, obviously. Haven't you watched any anime?" #MiniaturePainting #Warhammer

Miniature of an orc with a heavy red armor and a large chopper.

One of the big advantages of buying the physical book of a webcomic is that you already know you like it, but now you can have it in a nice and convenient format! #SideQuested bt @alepresser.com and @kbspangler.com, and #Aurora by Red of @overlysarcastic.bsky.social

The yellow Orconzola now has two companions: Big Boy Blue, and the greenest Green Knight. I am still absolutely terrible at both blending and basing, but I think I am slowly getting a hang about edge highlighting and gaining some brush control. #MiniaturePainting #Warhammer

Painted miniatures of two orcs, one on the left with a bright yellow armour, and one on the right with a dark blue one.

Jacopo Bertolotti@jacopobertolotti· Apr 11

Due to its yellowness, a friend of mine dubbed him "Orconzola", so this is now his name forever. #MiniaturePainting #Warhammer #Orc

Painted miniature of an orc in a heavy yellow armour with a crude sword and a huge shield

Jacopo Bertolotti@jacopobertolotti· Apr 5

One more finished model, a million new things I tried for the first time. The most notable were blending contrast paints, and the crackling on the base. Biggest mistake was not to undershade enough before applying the contrast paints. #MiniaturePainting #WH40k #Warhammer

Painted Tyranid prime (from the WH40k starter set).

I haven't been here in 20 years. When I was a student, Physics at the University of Florence was in this old, beautiful villa on the hill of Arcetri (not far away from Galileo's villa). 1/2 #UniversityOfFlorence #PlasmonicaSchool

#PhysicsFactlet Scattering VS Extinction In #Optics, the concepts of scattering and extinction are closely related. So closely related that many people tend to confuse them. 1/ 💡 ⚛️ 🧪 🎢

Coupled dipole simulation the the scattering of a Gaussian beam from a point particle.
The image is divided in two rows of three images each. The top row show the electric field (in blue and red), while the bottom row show the modulus squared of the electric field (in green), which is proportional to the intensity. The three columns show the incident field, the scattered field, and the total field.

#PhysicsFactlet While electrodynamics is well understood, there aren't many scattering problems we can actually solve. A plane wave scattering from a uniform dielectric sphere is one of those few, and the solution was originally found by Gustav Mie in 1908. 1/ 💡 ⚛️ 🧪 🎢
