I guess that I can explain a little bit what I do. I'm a PhD student at the Université Libre de Bruxelles. My main interests are Numerical Calculus and GPU computing. I also produce some music and am involved in game development.
I'd be glad to interact with you all!

Hi, I am Marco from Milano.
I am PostDoctoral researcher, working in the field of the Large-Scale-Structure of the Universe. I am a member of the @esa #Euclid space mission, aminly active in the Galaxy Clustering Science Working Group.
I am also interested in high-performance computing, with an emphasis on modern languages such as #julialang and differentiable programming.
On a personal side, I live in Bergamo with my partner and I am an amateur StandUp comedian.

I’m here to talk about baseball, galaxy formation, academia, etc., but the real reason I’m here is because I can’t get the song “Mr. Mastodon Farm” by Cake out of my head.

#introduction time now that I'm ready to start trying mastodon out!
I currently work as a data scientist in the population health realm. Our team supports public health decisions. Previously, I was a research astronomer; my PhD work was on #exoplanets.
I'm a dad to 3 kids, 5 and under, and we live on unceded Snuneymuxw territories.
On Mastodon, I hope to stay in touch with astronomers and meet other cool folks! I'll probably toot about parenting and science.

"His master's oscillators" 😊
«In the world of #renewables, #lithium_ion #batteries are storage kings, making up around 70 percent of electric vehicle (EV) and 90 percent of grid batteries around the globe. As such, they’re becoming increasingly important in a world that’s trying to reduce its carbon emissions by electrifying homes, cars, and more. (Not that mining for lithium or the various rare earth metals in battery production is carbon-free.)
However, there are some problems with lithium-ion batteries, according to a recent Atlantic Council report. For one, existing #supply #chains for the #minerals used for batteries are likely to be pushed to their #limits as the world transitions to renewable energy.
But there are also #geopolitical factors that could disrupt these supply chains. For instance, many of the minerals tied to the production of these batteries are either obtained or processed in Russia and China. For the United States, this might mean that the security of the supply chains for these batteries is put at risk by geopolitical #conflicts. For instance, Russia’s invasion of Ukraine saw the price of nickel—a core component in EV batteries—skyrocket.
...
“Our main conclusion in this regard is that: What policymakers and the private sector really need to consider is this big-tent approach on battery storage. Naturally, we expected lithium-ion batteries [will have] a starring role, as it were, in the energy transition. But these #alternative #batteries are going to have an increasingly important supporting role,” Ryan said.
“We need all of these [battery] chemistries to be brought to market at scale as quickly as possible in order to relieve the pressure that exists on current lithium-ion supply chains,” he said.»

My #introduction updated: I'm a #poet, #tech worker, occasional #gamer, novice #birder. I #sail when I can. I'm handy with #knitting needles, #sewing machines, #crochet hooks and #tatting shuttles. I read all sorts of #books. I'm curious about this world and love when someone has deep dives on topics of interest. I avoid the drama. I trained in #science. I support social justice. Say hello 😺 (she/her)

#UMPlus - NGC 1499 by J. P. Metsävainio
https://www.universomagico.net/2022/10/ngc-1499-por-jp-metsavainio.html
NGC 1499, popularly known as the California Nebula and seen here in a rare and detailed image by astronomer JP Metsävainio, is an emission nebula located in the constellation Perseus not far from the open star cluster Messier 45, known by the name of Pleiades. California is located at a distance of about 1,000 light years from Earth. Its name comes from its resemblance to.....

I made this in April for @jonnajinton video project, but since there are still no news about it, I decided it to post it anyway :)
It's also a little behind the scenes video from my animation project I'm working on.
Love for all ❤️ 🌈 🦉

We should be worried, because some folks think a limited nuclear war is possible and winnable. It isn’t!!
A nuclear war simulation shows the devastation we could face if one country pulls the trigger
The simulation shows what would happen in the aftermath of a roughly 1,200-warhead nuclear attack on the United States.

Time Complexity (Big O) simplified:
- When your calculation is not dependent on the input size, it is a constant time complexity (O(1)).
- When the input size is reduced by half, maybe when iterating, handling recursion, or whatsoever, it is a logarithmic time complexity (O(log n)).
- When you have a single loop within your algorithm, it is linear time complexity (O(n)).
- When you have nested loops within your algorithm, meaning a loop in a loop, it is quadratic time complexity (O(n^2)).
- When the growth rate doubles with each addition to the input, it is exponential time complexity (O2^n).

New image of the planet Jupiter taken last night from Isabela, PR. In this image, you can clearly see the Great Red Spot and the moon Io to the left of the planet.
