What are standard tapers, that are generally used? I wanted to order some labware, but the dimensions are different for each part.
I thought 14/23 and 29/32 are almost exclusively used, but eBay, amazon, and some smaller websites offer a fuckton of st dimensions, like 19, 24, 34...
Is this a region-specific thing or am I missing something?

>> No.12414715

Yes, I wanted to buy everything with a 29 or maybe 14 standard taper, but I found that most online shops sell parts with other sizes. That's why I asked here, sorry if I wasn't clear. I wanted to know if other sizes are more widely used, before buying a bunch of parts, that I now need adapters for.

It's relative. There's no absolute up, down, left or right. The universe doesn't come equipped with coordinates.

It's why we use the dot product instead of direct multiplication.

Education is designed to teach you as little as possible. The overwhelming deluge of information is intended to drown anyone who stops to smell the roses. There is not enough time to understand all the content and process it into knowledge. Not having time to think forces you to download your ideas from others. And this is deliberate. You’re not meant to comprehend any of it. You’re mean to rote learn and regurgitate torrents of incoherent rubbish on command under a stopwatch. This is the object of schooling.

This is an exercise in compliance, repeated and conditioned until you lose the ability for independent thinking. Schooling punishes enthusiasm and rewards obedience. Education is about showing up and motioning through the movements without question or resistance until you are domesticated with a low-resolution mind.

This is little to do with learning. Leaning is about questions and answers, not propagating someone else’s ideas. Repeating what you’re told is not intelligence. It’s nothing to be proud of.

There are people who believe that memorizing formulas and repeating algorithms constitutes actual thinking. These people really believe they are engaging in thinking when they do this. Imagine spending 4 years listening to the inane gibberish or a university and actually believing you learned something.

If you are willing to play these silly games, you can climb the ladder. For the NPCs who excel at these dog tricks is the reward of writing their egos a blank cheque as titles and accolades are piled on and they graduate into a world of management and system maintenance. And these people do function. Many of them as high-functioning. But that’s all they do; function. They do not think.

yup, all the while the world is facing threats that need innovative multidisciplinary approaches. the institutions are continuing the plutocratic ivory-tower drivel that worked during the industrial revolution but no longer bears fruit to the extent required for meeting the challenges to be faced by our species. Through a thousand small cuts in the form of nepotism, privledge, myopia, and cognitive inflexibility these institutions will fail to meet the needs of our societies. The wealthy will brush shoulders with the wealthy and claim their so called meritocracy while the world begs for innovation and does not find it. Our society is at a precipice and it cannot afford the structures of old that we're just good enough to give us alternating current, the hadron collider etc. To have levels of innovation required to meet our needs we must look at the ways in which we currently exclude those whose talents are wasted, address the glaring inequities in education etc,

This is true, but I think there is value in getting the general idea of a wide range of subjects. For example, I'll probably never need to use the techniques taught in differential equations again. But if I needed to for some reason, I'm confident that I could learn them fairly easily because I have that foundation.
It's impossible for educators to predict every intellectual tool you're going to use in the course of your career, so the best they can do is expose you to a wide range of subjects, so if you need to you can fill in the gaps later.

However, spike proteins also contain syncytin-homologous proteins, which are essential for the formation of the placenta in mammals such as humans.

What's the difference? Her conditions weren't met so Google started a conversation about her end date and decided it would be immediately. Would it make a difference if they said "okay your end date is tomorrow"? What about next week?

I get that it's a courtesy for you to give notice and also think firing someone immediately because of at will employment is wrong but there are definitely industries where, for security reasons, you are escorted from the premise and have all access revoked the minute you announce your intention to quit. I'd imagine AI at Google is one of those industries. This just sounds to me like she willingly put her termination of employment on the table and she's surprised Google took it.

And I'm not commenting on whether blocking her paper is censorship or not or if it was unethical of Google to "fire" her over this issue because that's a different discussion. Why is this even being framed as her being fired when she offered to resign?
