Why do so many flat-earthers believe in a god they can’t see and say that they don’t need actual physical proof that god is real…….

But when it comes to the earth being round they are all like “ well I can’t see the curvature of the earth so the earth can’t be round” and completely dismiss years of documented physical scientific proof?

The silent “sixth” sense

Proprioception is the body’s mysterious ability to locate our limbs, even in darkness. We’re just beginning to understand it.

By Brian Resnick

The mysteries of proprioception

Touch is complicated. Proprioception might be even more so. But in studying it, researchers may yield discoveries and applications that stretch far beyond the human body.

Deep in all our muscles are fibers called muscle spindles: This is a bundle of fibers and nerves that record muscle stretch. On the nerves endings of the muscle spindles, yes, you’ll find piezo2. When the muscles are stretched, others contract, and piezo2 then transmits all that information to your spinal cord to determine where your limbs are.

What’s amazing is how every muscle in your body is sending out this information all the time. Your nervous system somehow processes that massive amount of data without any conscious work on our part. How could it possibly be conscious? You’d go wild from information overload.

Just think of what it takes to sit up straight. All the muscles in your back have to relay the right information so you can keep all the bones of your spine in line. The piezo2-less patients don’t have that. They have scoliotic posture because they don’t have the muscles in their back telling their brains how to align their spine. (Many of these patients, I’m told, are also malpositioned in the womb before birth, or are born with hip displacement — that’s how fundamental of a sense proprioception is.)

Lacking the primary input for proprioception, Sana and Sausen have to concentrate hard to not feel disoriented. Sometimes, Sana says, just her hair getting in the way of her eyes will cause her to lose orientation of where her body is. The same can happen if someone gets too close to her face, blocking her peripheral vision. Which means she needs to concentrate extra hard if she wants to kiss someone.

It’s still a deep mystery how the brain pulls together all the sources of proprioceptive information so effortlessly.

“The most amazing this about it is how utterly flexible it is,” says Adam Hantman, a neuroscientist at the Howard Hughes Medical Institute who studies proprioception. “You can ask me to reach out for a cup, and say, ‘Don’t do it in any way you’ve ever done it before,’ and without practicing, I could snap my hand around upside down, put it behind my back and reach that cup. I’ve never done that action before in my life, and I could do it without practice.”

And there are so many beautiful complications in this research still not well understood by scientists.

Scientists generally regard touch and proprioception as different systems. “But they can overlap to a certain extent,” says Joriene De Nooij, a neurology researcher who studies proprioception at Columbia University. Receptors in the skin contribute to our understanding of where our limbs are. “When you’re walking there’s all these pressure receptors in your feet that will be activated every time you take a step,” she says. And that also gives our brains information about where the body is.

We have so, so many inputs into our sensory system that give us feedback and orient our minds to what our bodies are doing. “Learning how the brain actually pulls this off — what are the algorithms it uses to build these models and utilize them — will help us make better machines,” Hantman says.

Particularly, it may help researchers make better prosthetics that are directly controlled by an amputee’s nervous system. “The machines are pretty good at taking a signal from the brain and making the prosthetics move,” he says. “But we really haven’t done that great a job closing the loop, getting sensory information back.”

The brain also does another thing involving proprioception that researchers deeply want to understand: How it compensates in the face of loss, like in the cases of Sana and Sausen.

The most remarkable thing the brain can do

The muscle spindles and other nerve endings explain how proprioception works in the body. But even stranger is how it manifests in our minds.

I keep thinking about what happens when I close my eyes and reach for something. There’s a glass out in front of me on my desk. I can still grab it with my eyes closed. I’m trying to concentrate on the thought of where the glass is in space, and dissect it: What exactly am I experiencing in this moment?

It’s a totally random thought but I wonder what will happen if Senku and Haibara meet in a Detective Conan x Dr. Stone crossover? 🤔

💭 This is exhilarating!

  • They’re both man and woman of and for science
  • They’re both developers of drugs for entirely different purposes- one is APTX4869, one is antibiotics for ushering in an era where humans can put up a fight against microbial infections.
  • They both come off as arrogant to some degree imo 😊
  • They’re older than they look They’re both ‘trapped’ in a body much younger than their original selves ie. Haibara is 18 yet her body is 7, Senku is 3700+ years old, his body is that of a highschooler.
  • They both have a second shot in life.

Наверное, многие помнят из школьного или университетского курса химии или биологии пипетку как длинную стеклянную трубку, куда нужно набирать содержимое грушей. А если груши нет, что часто случается в бюджетных учреждениях - то ртом! Ходят байки, что таким способом пользуются в некоторых поликлиниках, когда делают пациентам анализы на различные инфекции

Однако времена этих приспособлений давно прошли! Когда требуется точность, стерильность и безопасность, использовать можно только современную пипетку (дозатор), которая позволяет отобрать необходимый объем жидкости. Например, на втором фото установлено значение 29 микролитров, а на третьем - 129. Объем, который можно отобрать пипеткой, ограничен. Самые маленькие позволяют отобрать от 0,1 до 2 микролитров, самые большие - до 10 миллилитров.

Жидкость набирается не в саму пипетку, а в одноразовый наконечник, который может быть стерильным и даже содержать фильтр. Поэтому не пачкаются ни пипетка, ни образец.
Пипетки используются учеными многих направлений и имеются во всех лабораториях, где работают с небольшими объемами жидкостей.

Hey, fellow writers, if you need clarification on something science-y but don’t want to read through long articles or watch boring videos that might leave you confused, I suggest Veritasium on YouTube. His explanations are pretty straightforward and fun to watch.

Here is a video of the science behind the Butterfly Effect that I really enjoy:

Iapetus

3rd largest moon of the Saturnian system. It’s distinctive colour of half white and half black make for a visually stunning scene, creating a yin-yang pattern upon the moon.

The colours lead to a large temperature difference, with the dark material around -144′c and the white material -160′c due to head absorption on the darker material. This in part also explains the difference, having created a runaway condition where the extra heat prevents the white material forming, which means it receives more heat !

Just a thought

Personally I feel ,despite a few pictures of my notes that I’ve put online,I tend to study better when my notes are messier and lacking colour rather than when they are neater,more organised and full of colours.

Perhaps I get too distracted by the colours of in the paper?

But sometimes it works the otherway around.Sometimes

For example ,take a look at my physics notes

image
image

It was an absolute mess,because I covered five chapters worth of notes in two hours(not sure if it’s much for you guys,many of you are far more experienced and have probabaly done a more vast portion in lesser time)

But somehow the marks I achieved weren’t so bad when I did revision based on this

But on the other hand for my bio notes

image
image

It’s far more neater ,has some colour I guess ,yet I managed to get around a 70 for bio

Although one might say these subjects are completely different things,I most definitely agree,I would love to see if there is any change in my results if I start studying with more messier notes perhaps for the next term?

Of course I will have a book for neat notes separately just in case.
