I have a couple that could qualify, if you stretch it a bit (or a lot), but they're more fun than science.Given the relative viscosity and density of water I'd say it would be more like burrowing through treacle than swimming. I remember a comment about bacteria with flagella that it was like mining through warm tar size for size.
Anyway, here's a tardigrade swimming:(https://media.giphy.com/media/GAWlF4fPkrF2o/giphy.gif)

That's so clever but sobering. Is that meant to show what happens in MS-type conditions?

I think so. With the loss of myelin sheaths our neurons can no longer communicate. Some animals such as invertebrates do not have myelin, but their axons (the long projection) are so wide that there is little physical resistance for the electrical signal, which can get through. A squid's giant, demylelinated axon is visible to the naked eye. :o

Wow! Giant axons. Hmm wonder when sci-fi will strike and they attempt to grow a "squidputer"?
True, is it a matter of manipulation or encouraging the axons to behave as you want them? Even the real thing is difficult to keep under control, let alone some lumo of jelly in a container connected to the outside world to make a biologucal computer.That's so clever but sobering.

Why squid? Our mylienated neurons are much faster, and besides that you can fit many more "wires" in an area!

These GIFS show you what it's like to be colour-blind (http://www.iflscience.com/health-and-medicine/these-gifs-show-you-what-it-s-like-to-be-color-blind/)
That's a clever way to show what it's like to be colour-blind. Is there any evidence that people with the condition suffer with depression because of it, or is just their normal and not a cause for sadness? As they grow up they must become aware they are not having the same experience as everyone else.

Interesting. Not sure if it is accurate or not. I am color blind and my wife is not. We looked at them together. We could both see the differences in all the gifs. Here is a beautifully vulgar display of taking advantage of the color blind.

I have never heard of anyone being depressed because of their color vision deficiency. I have certainly never experienced it for myself. Everything looks the same to me as it did when I was born. There have been people who have made fun of me for it but there have also been people who have made fun of me for my hair, my height, my weight, my political views, my religion or lack thereof, my sexuality, my service in the armed forces, the color of my skin, my ignorance and my sense of humor. It doesn't matter who you are, what you are, what you believe. There will always be someone there to ridicule you for who you are. These things shouldn't matter. At least, they don't matter to me. If some Democratic "leader" wants to give me some money taken from you to compensate me for my "disability" then they can shove that particular carrot up their ass.
I am a pressman. I operate a four color offset press and I produce beautiful work with a printing machine very similar to this one.
Maybe some people get depressed. Maybe some people use a Gretag MacBeth DC19

A 'No' then. I'm pleased, but sorry to hear you had so much teasing. To have as much as that was verging on bullying surely?

Yeah but my parents instructed me to tease them right back. It worked well for me in elementary with the small group of kids I grew up with but in Jr. High we were scattered to the four winds as five or six elementary schools were all mixed together. I became depressed and bitter but continued to shoot back at people who teased me. I never let it show that it bothered me in the least. In fact, I usually teased them back with a big smile on my face like we were just playing a game. By the time I got to high school I could no longer tell the difference when someone was actually threatening me, looking for a fight, or just clowning around.
Looking back, I had a lot more friends than I realized at the time. After high school I ran into some of the guys I considered enemies at the time because they teased me the most. Turns out they remembered things differently. They remembered me as having the toughest skin, that nothing ever bothered me and they lamented about how they wished they could have been as strong and fearless as I was. They even got into a minor disagreement about who was my friend first or who knew me the longest. It was surreal.
So, what I described in my previous post does sound like bullying but it was just the games we played growing up, testing each other for weakness. It was universal in that we all made fun of each other pretty equally even though we each felt that we were getting picked on more than the others.
In my mind, bullying entails a concentrated effort to systematically isolate one individual for special ongoing constant abuse, usually over one specific aspect of their personality or lifestyle. I didn't experience anything like that. What I experienced was a whole bunch of people throwing random shit against the wall to see if anything would stick.
I'm glad for you that you did not feel you were bullied. You must be very quick-thinking to have been able to come up with an effective reply to the teasing. Would you say you are an example of 'what doesn't kill you makes you stronger'? And do you feel you have friends now to a greater extent than before? Questions, questions; but that was such a moving and fascinating reply and I'd like it if things are better for you now.

You got that right. In reply to your first sentence, I'm a bit tardy myself - don't know how I missed this. I visit two or three times every week still because it's the only forum I'm in and I enjoy it. I was visiting all day every day at first because it was a bit seismic realising I was an atheist, and finding lots of regular folk (well actually quite singular types; intellectuals, comedians, scientists etc), for whom lack of religion was normal, was reassuring.I'm glad for you that you did not feel you were bullied.

Please accept my apologies for taking so long to respond. I don't visit this site very often, I am sorry I kept you waiting. It's just that I only just now looked back over my previous comments to see if anyone has responded. Life can be rather hectic sometimes, you know?
What doesn't kill me makes me stronger? Yes, maybe, but only in the figurative sense. But there are trade off's. I am far less empathetic than I used to be. I have developed the ability to insulate my feelings at the expense of caring for other peoples feelings. It's not a total wash but I can tell the difference. It's not that I don't care what other people feel, it's just that I don't think about other people's feelings as much as I used to. If other people are polite and courteous to me, I am polite and courteous to them. If they are not, I reserve the right to treat them as poorly as they treat me. It's a situational thing and every situation is different.
As far as my friends go. I feel I have just as many now as I did at anytime during my childhood. One. The one changes from time to time as people go about their way. I have had many "best" friends over the course of my life, usually only one at a time. Currently, my best friend is my wife.
My approach to life has not benefited me financially but I know that I will die with few regrets.
Things are no worse for me now, but they are no better.
People are strange.

I really need to watch that series. I only watched the original, with Carl Sagan.
Essie Mae you can, if you wish, have many casual or semi formal friends by simply networking. My wife is something of a social animal who has about a gazillion friends and acquaintances. She is a Red Hat lady, a member of ABWA (American business womens' association), and a few other groups such as her investment club ladies who have not bothered with investment subjects for years. Those girls just have a hell of a good time with one another and are not much concerned with whether or not they have the approval of the general run of society. They often get together to attend theatre, have dinners, drink too much wine, and laugh a lot. I am inclined to think that British ladies are not all that much different and that they can also have a hell of a good time together without hurting or diminishing anyone whatever.
Meanwhile... I am glad that we have you, EM, here on this forum.
That play, the Full Monty, is a fun show to attend. It is actually not so bawdy as to offend the general run of theatre goers. Encourage your friend to let her hair down a bit and to laugh a lot because that kind of behavior is healthy.I'll see what I can do. 😉

"Neuron to dendrites... Are you receiving?"
One of the most common questions you'll hear from people who don't want to get vaccinated is: "But if the people around me are vaccinated, why does it matter?"
And the answer isn't entirely straightforward, because both the reason this person needs to get vaccinated, and the reason they feel they don't have to, come down to the same thing - something called 'herd immunity'.

Incidentally, what are the applications of sine waves?
Another curiosity: Imagine that you have attached a tiny light to the bottom sidewall of an auto tire. When the automobile moves, the light will describe a half sine wave.

I may be wrong, but I thought the light would describe a cycloid curve?
OK how 'bout we toss a rock toward the nasty neighbors window, and trace its path? Sinusoidal? ....
To take the wheel and light setup further, if one did not place the light on the rim, but somewhere else on the wheel, would its path still be a cycloid?
Dead centre, on the axle, the path would be a straight line, but what about, say, halfway along the radius? Or even at a point beyond the rim (greater than the radius)?

This is where maths and me hit head to head!
I can see that it is possible to generate a formula that, taking the rotational frequency and the velocity of linear motion of the centre of a rotating disc, decribes the resultant wave form. But I have no idea of how to even start on it!
So i would turn to physical, mechanical means, making wheels etc, and then, possibly, deriving the math from measuring actual examples. Don't have the skills to write an algorithm either!

Is that a bit like what Gaudi did? To work out building stresses he hung loops of chains in the relative sizes of his planned buildings and derived the formulae for his designs from that. At least, that's what ESs of little brain understood.
I don't think I have revealed this before, but I have one great hero, Charles Eames. No, not a scientist, but an architect and designer. He is one of the famous people I would have liked to meet, but unfortunately, just before that was due to happen, he died unexpectedly in 1978. I have been collecting his furniture for many years. Anyway, this is one of his famous quotations about connections:
Eventually everything connects — people, ideas, objects...the quality of the connections is the key to quality per se...I don't believe in this 'gifted few' concept, just in people doing things they are really interested in doing. They have a way of getting good at whatever it is.
