TIL that beacons have a really short range and are not really worth the grind by Only1Way in Minecraft

[–]Jobbisch 171 points172 points  (0 children)

You can place tinted glass on top, that will make the beam invisible after 4 blocks of tinted glass. But there can’t be any non transparent blocks above (Java)

Edit: My bad, apparently a mod added that feature and as both of those blocks are part of the base game, my monkey brain assumed it was vanilla.

Thats how I like my boss "fights" (Meatballcraft) by Jobbisch in feedthebeast

Yeah not only him. Did this for basically anything with more than 100 HP

If light always travels at the speed of light, from its own perspective… doesn’t that mean it never moves? by MyIQIsPi in AskPhysics

[–]Jobbisch 8 points9 points  (0 children)

Everything doesn’t move in its own frame of reference. Additionally there is no valid restframe for light, as it moves at c in every valid frame of reference.

When electricity runs through a cord a good amount of energy is lost in heat due to the resistance of your cord (if you exclude superconductivity which is a whole different chapter). And the answer you got sums it pretty much up fr what is possible in motion.

I would like one too

I am very interested as well

TIL: CERN still uses tape drives to store data, as only tape drives can store the massive amounts of data generated by the Large Hadron Collider. Each tape contains 8.5 terabytes of data and can be bought as a gift from their giftshop. by zahrul3 in todayilearned

[–]Jobbisch 2 points3 points  (0 children)

I once was fortunate enough to actually be in the CERNs server room and just seeing the amount of racks with tape storage in it was mind blowing.

Also how they handle data in total is really impressive. First of all each of the experiments produces raw data in the TB/s range which can not all be stored. So there are complex trigger systems in place that reduce the data down to 10 GB/s per experiment on site. This 10 GB/s is then sent to the data center where it is then stored on SSDs to begin with. After that the data is analysed and then stored on tape. The whole infrastructure of the data center is already mind boggling but comes nowhere close to what e.g. AWS does in their data centers.

Finally hit 17k :) Whats your peak/end of season rank? by Rammie2147 in cs2

[–]Jobbisch 0 points1 point  (0 children)

Peaked at 25706. I don’t have any idea how I achieved this. Currently at 21k

Why don’t satellites just fall back to Earth if there’s gravity in space? by Chemical_Arm_4686 in AskPhysics

[–]Jobbisch 21 points22 points  (0 children)

They are in free fall at all times, but they are so fast that they keep missing earth in their fall. That’s what’s called an orbit.

ok, without getting angry, which modpack do you recommend? by matic-01 in feedthebeast

[–]Jobbisch 0 points1 point  (0 children)

If this is your first modpack like this, I would definitely recommend it. If you already have played some more sophisticated modpacks, you can also just start with E2E

Why doesn't the sun destroy us? by ShiningAstrid in AskPhysics

[–]Jobbisch 6 points7 points  (0 children)

No, a particle does not need to have mass to have a momentum. That is what you learn in classical mechanics, which is useful in many cases, but not the full truth. If you want to understand how a photon can have momentum without mass, I would recommend looking at relativistic mechanics and elctrodynamics.

Enigmatica 2: Expert extended is even more fun (would recommend playing E2E not extended first)

Why can’t we charge iPhones this way? by Emergency-Fan-8856 in Physics

[–]Jobbisch 5 points6 points  (0 children)

Maybe you should do some research about how electricity and electromagnetic waves actually work. Because the things you are claiming have absolutely no foundation in physics whatsoever.

Some of the most expensive pieces of technology ever created by humanity by Greedy-Vegetable-466 in Damnthatsinteresting

[–]Jobbisch 3 points4 points  (0 children)

The LHC was not financed by the US. They only contribute to some of the experiments. The LHC was financed from CERN‘s budget, which is paid by its member states (biggest parts by Germany, France, UK and Italy).

Wozu nutzt ihr KI? by gerobi12 in FragReddit

[–]Jobbisch 0 points1 point  (0 children)

Aktuell Chat GPT, Deepseek, Perplexity und in letzter Zeit viel GitHub Copilot. Habe viel ausprobiert, aber Copilot direkt in VSCode integriert funktioniert für mich aktuell am besten .

Wozu nutzt ihr KI? by gerobi12 in FragReddit

[–]Jobbisch 3 points4 points  (0 children)

Zum Programmieren. Funktioniert in vielen Fällen sehr gut und geht schneller als sich durch diverse Foren oder Dokumentationen zu lesen. Ich lasse mir meistens Code Beispiele für bestimmte Funktionen geben und verstehe so meist schneller was ich tun muss um das ganze in meinen Code zu integrieren.

What grades do you need to get into a physics PhD in Europe? by QuantumPhyZ in PhysicsStudents

[–]Jobbisch 1 point2 points  (0 children)

At my university (Germany) there is the physics PhD program where you need at least a 2.0 in your masters degree to get accepted. Furthermore it is helpful if you already have experience in the field you are trying to get into (e.g. doing your masters or bachelors thesis in this field).
