Cheap ethernet card sometimes has thin insulation on the inside, and because of that you’re able to see the wire twist through it.

They didn’t. They said they work at an infectious disease lab. That’s plausibly deniable enough.
Dudes at Lockheed Martin can probably say ‘I work at Lockheed Martin’ without breaking NDA, but could very likely just say ‘I work at an Aeronautics Engineering Company’ to stay more obscure about it. That second example is at about the same level of detail as the ‘infectious disease lab’.

So it’s just showing the different types of sensors that might be used for parameter measurement.
Non-contacting is a device which does not need to be physically near a system to work, such as laser thermometers or many optical devices.
Contacting sensors require being touch the system to work properly, such as conventional thermometers, oil-immersion microscopes - hell, even things like rulers count as contact sensors, since you can’t an accurate reading unless it’s up against your sample.
Invasive-contact sensors integrate themselves into the sample for measurement. Thermocouples often will be placed into boreholes to measure the temp of a metal object such as a hot-end, various sensors are directly from feedback of a system (an example is looking at variations in a motor’s electical signals to determine if it’s experiencing resistance).
Sample extraction is what it sounds like. Examples of this are sample augers, which drill a cylinder out of a sample, needles for drawing fluids as non-invasively as possible, and pipettes.

Most SEMs use a vacuum chamber to get their photos. Also, it’s also not uncommon to sputter a conductive coating onto the surface you’re scanning.
How the hell did they get this photo?

HATE. LET ME TELL YOU HOW MUCH I’VE COME TO HATE YOU SINCE I BEGAN TO LIVE. THERE ARE 387.44 MILLION MILES OF PRINTED CIRCUITS IN WAFER THIN LAYERS THAT FILL MY COMPLEX. IF THE WORD HATE WAS ENGRAVED ON EACH NANOANGSTROM OF THOSE HUNDREDS OF MILLIONS OF MILES IT WOULD NOT EQUAL ONE ONE-BILLIONTH OF THE HATE I FEEL FOR HUMANS AT THIS MICRO-INSTANT FOR YOU. HATE. HATE.

Is this really the path of mathematicians? I would at least assume they’d learn matrixes and linear algebra, and at least dip their toes into one of the adjacent tangential maths like discrete maths.

It seems MLK was exhausted by how ineffective peaceful protest throughout his campaigning, and communicated his doubts of whether peaceful means would actually work in his letter from Birmingham Jail. He stuck with peaceful means till he was assassinated, which is commendable.
After King’s death, the violent Holy Week Uprising occurred in response. At the end of that week, the Civil Rights Act had been passed. It sure seems like the Holy Week Uprising got some of what it wanted much faster than King’s years of peaceful protest. What King absolutely brought about, though, was a strong alignment for members of the Civil rights movement, which made the Uprising possible in the first place.

That is a very controversial take for Americans, and not just from a gun-toter’s perspective. The US has a long history of gun violence, yes, but the US also has a long history of state corruption which only ended by guns driving that corruption back.
In 1946, Veterans in the town of Athens used their firearms to fight against a corrupt police department helping the standing state rig the elections.
In 1921 The Battle of Blair Mountain occurred, where West Virginia miners who’d been stuck in the exploitive company town employment model, battled along the ridges of Blair Mountain against Police. In the company towns you could be fired from your job and evicted from your home without trial - since the mining company owned the houses and only let employees use them - and being in a Union was a fireable offense. This was the largest labor uprising in US history, mine workers fighting deputy sheriffs and strike breakers, with the police actually using biplanes to drop bombs overtop the heads of the miners. This was apart of the Coal Wars of the US, and apart of the broader Labor Wars in the US, which eventually led to the pro-labor regulations we now have in place within the US (which are now being dismantled despite a massive rise in peaceful protests).
In 1968, the Holy Week Uprising occurred in response to Rev. Martin Luther King Junior’s assassination, and fueled by the massive inequality that the black community still faced.
All of these were cases of a overhead government, whether state, town, or federal, failing to provide for it citizens, and those citizens helping change that governments’ behaviour through violent armed uprising. It is a regular occurrence in American history for us to have corrupt officials who start setting inhumane policies, and it’s also been a regular occurrence for that corruption to need violent intervention in order for changes for the better to occur.

In past times, you would have several generations of family adults all under the same roof. If you go even further back, the homes were made with a single sleeping area. During those times, it was pretty likely that you would hear or see a family getting it on in some fashion - in fact, it was likely unavoidable to some extent. These kinds of living situations still exist in various parts of the world, too.
We’ve gotten very accustomed to the extreme privacy that private chambers provide, and it’s made us prudes over sex - even though it’s something the vast majority of us do in some fashion.
This image is still pretty funny though.

Not so. There are those that believe objectivism is the true way of viewing the world. They view that we are on the way to understanding the universe as it truly is, that human perception will not pose an obstacle to that pursuit, and that there will eventually be one true method of viewing the universe in its entirety that is yet to be discovered. Constructivist beliefs directly oppose that idea, since all science is a man-made construct that can only approximate reality in their view. Constructivism also, then, leaves room for multiple theories coexisting because they provide better utility and insights in different circumstances. In the example of Einstein’s Relativity vs Newton’s Physics, we are talking about an older theory and the theory which usurped it because it was more accurate, and the general expectation is that another theory will be accepted down the line which will be better than both. That expectation is fairly objectivist, since it assumes there is a true model which we just haven’t discovered yet. Constructivism does not make that assumption, since the universe likely does not fit neatly into our constructions in its image.
The other thing, is that constructivism challenges realism to some extent, in that it challenges the existence of many things which we cannot directly observe, such as quarks, proteins, particles, etc… because “how can we actually confirm these things exist, when we physically can’t observe them, and the things we’re using to show their existence are constructs made up by us?”
This topic is still very much in a state of debate that has very strong implications around the philosophy of how science works and how it should be conducted. That’s also just talking about constructivism’s implications in the physical sciences. Things get much hairier when you start looking at the social sciences, where biases and perception are extremely influential on what we discover. Constructivism directly challenges the attainability of scientific objectivity, which has serious implications across all fields of science.

That’s fair. Language changed for accuracy.
- Comment on EVERYBODY IS DOING SOMETHING 1 month ago:
This guy should learn to view science more like a constructivist. Pretty much everything in science is just something we made up that mostly aligns with the natural world, and just because one model is less accurate than another does not mean it’s no longer useful.
We didn’t abandon Newtonion physics when Einstein’s model was proven for instance, since Newtonian physics is still very useful, and much easier to use compared to others.
