I have a couple that could qualify, if you stretch it a bit (or a lot), but they're more fun than science.

Anyway, here's a tardigrade swimming:

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.

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

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

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.

Was thinking that larger ones might be easier to work with, even manipulate mechanically into arrays etc.

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.

Good question!

I don't know the answer but I would assume that there might be some people within the colour-blind population that might feel that way, but I don't know if their number would be significant enough to link depression to the condition.

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 only know what it says because my wife told me.

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

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.

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?

QuoteA '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.

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.

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.

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.

Thank you for your thoughtful reply. Like for like treatment of people seems a good way of preserving sanity. Having one good friend is better than many acquaintances IMO. I have five friends of very long-standing from different times of my life from age 11 until 22 years ago, which is when I made my last friend. The funny thing is that none of them get on very well with each other. I suppose they are a disparate lot but I do sometimes wish I had a group of friends to meet with on occasion. Not since my teens has that happened. My husband has only one friend, but he sees a lot of his family who all live quite close. You seem to have made peace with your situation and I wish you well.

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.

That is so lovely🙂 Thank you. I don"t want to give the impression I'm unhappy; it's just that all the people I seem to meet on my organised walks are lovely but fairly quiet and serious. My closest friend and theatre buddy is the same; I count myself lucky to have her, but, for instance, I'd like to go and see 'The Full Monty' which is on at the Cambridge Arts Theatre in January, but my friend would think it a bit beneath her. It would be hilarious to go in a group. Anyway, I've got Australia and my granddaughters to see in mid Feb, so I'm not feeling sorry for myself at all. I've been reading a report today about how people way younger than me are facing loneliness because of family break-ups and the like, and I've just realised I'm contributing to the derailing of this thread. It's what I do. Apols.

And the thing does that 50, 60, 70 times a minute for a lot of minutes.......1440 minutes in a day......times 60 means that those little valves did their thing 86,400 times. If a whole year is considered then thirty one million times and when one is as old as me, the total number is .......Oh Shit !........somewhere in the region of three billion. And that is only if the measurement was always counted at rest. Best not to think in those terms I reckon.

Yes, most of the shots show that extra brightening and thickening of the "trail". That is was convinced me it was genuine.

CGI is now good enough to be very hard to spot but immitating that, from several angles, would be quite difficult - not worth the bother.

There must have been a hell of a sonic bang as well, it was clocked at about 19km/sec, only about 60 times the speed of sound! But yes:

The article: "This Short Animation Explains Beautifully How Herd Immunity Works: Show this to anyone who asks why they need to get vaccinated." | Science Alert (http://www.sciencealert.com/this-quick-animation-nails-how-herd-immunity-works)

QuoteOne 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'.

Shows the problem well in a "random" distribution of infected/unvacinated where infection is determined by proximity/contact.

I am guessing the "geographical" distribution is important, you could get dense concentrations of "unvaccinated" in one are even with 90% coverage - leading to a larger number of infections.

Incidentally, what are the applications of sine waves?

Can't remember that gif, was it something like a spoke or radius rotating in a circle with the resultant wave form?

In both mechanical and electrical theory sine waves are very important, they are the "shape" of the electricity from your sockets, the basic shape of the "carrier signal" in radio transmissions and the shape of any pure audio tone. It is also the wave shape that would be drawn by a weight bouncing up and down on a spring. Remember the old "Spirograph"? That could draw sine waves if you set it up right, even sine waves in a circle to make sort of flower patterns - great fun!

The number of waves per second gives you the frequency, so a 1 kiloHertz tone would be 1000 full waves, or cycles,, like a "S" on its side, per second. Hertz was the guy credited with discovering this cyclic nature when he nannaged to transmit energy, through the air,  from a "transmitter" to a "receiver" - Marconi cashed in by sending "intelligence", a Morse code message, using Hertz' principles.



Wikipedia has, of course, an article on them: https://en.m.wikipedia.org/wiki/Sine_wave. The full name is "sinusoidal waveform"

Hmm, if you think of it a pen in a rotating disc with a sheet of paper sliding past under it - so the pen draws the sine wave on the paper - seems no different than the paper being still and the disc rolling along. The latter being analogous to the light/wheel set-up.

But you have me wondering now!

OK, checked on it, you are correct, Hermes, the rolling wheel gives a cycloid.

Something to think about there!

You two are both correct. The path of the light is in fact cycloidal. Shame on me for claiming otherwise. .... I had to lay it out on a sheet of paper to prove it to myself. That is a quirk of mine....the do it yourself thing.... it would be much easier to consult Wikipedia, which I did after the fact. Sure enough a good explanation is there on Wiki.  Better mental exercise to do it on a sheet of paper with the trusty calculator close at hand.  The presence of the calculator implies that there is a limit to ones dedication to mental exercise.  :cauldron:

OK how 'bout we toss a rock toward the nasty neighbors window, and trace its path? Sinusoidal?  That does have the critical exponent two in the equation.

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)?

We need a Spirograph to play with!

@ Icarus: "I need to see for myself", or, "I need to work it out for myself" has always been my problem in fully understanding, or perhaps accepting, things as well. It is not "real" unless I can see it physically demonstrated in some cases. There are, of course, things one just has to accept - building a nuclear reactor at home is hardly practical . . .

Not sure if being on the edge or half way across the tread makes much difference.

In terms of the sine wave or whatever being described a sort of "relativity" must come into place - the relsaive motions of the object (the wheel) and whatever is being "written" on. It is the conversion from rotational to linear motion, the relative position of a point on each component over time . . . sort of.

As for the space station: what is its "partner" in the "relativity" dance? Where are you, the observer, standing? This is a case of frequency of rotation versus the velocity of overall motion against the background. The rotational frequency of the car wheel is directionally proportional to its velocity on the road (assuming no wheel spins or skids!)- or its passing the stationary observer. The space station has no real constraints in the difference between its rotational frequency and linear velocity through free space. Thus a point on its edge could describe any possible shape, cycloid, a series of loops etc.

So, new question, what wave shapes are produced if the velocity if the linear motion of the rotating station through space is less or greater than its "equivalent" velocity if it was rolling along a surface?

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!

Seen several vehicles on Youtube that had other than circular wheels.

Thanks for the cool links Gloucester and Hermes.

This is a fun place to spend an inordinate amount of time.

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.

Yup, the good old empirical method, suck it and see!

It seems that many first attempts at building big cathedrals in the early middle ages ended up as piles of rubble, expensive piles of rubble. But, for the greater glory of god they kept trying, and it seems they learned a few things.

Now I can look at a shape and envision most of the forces in it, whether it will stand up or not, only because hundreds or thousands of people have built things that last and I have seen them and understood them. Would take me forever to work out the actual forces and stresses at any one point though! Just don't have the maths - and no inclination to acquire them!

But some ifvthe computer dedigns are increrible, like a web where each member is designed exactly to take its planned stress (150% to 200% of expected working stress say). Often looks like more air thsn matter! The video below is nit the one I wanted to find, but it serves, in parts.



PS
An old boss, mechanical engineer, had the idea that to lighten a structure and save material you drilled holes in it until it fell apart. In your second prototype you missed out drilling that last hole.

Yes, Gaudi and others as well. I don't know how Buckminster Fuller got to his geodesic domes, but I expect it was a more mathematical approach based on the known rigidity of a triangle.

This again shows how much is out there to explore, especially with the addictive internet searches. As some of us have said, one lifetime is not enough. As a child I could never just look up something in a dictionary or encyclopaedia without getting sidetracked; often forgetting what I was trying to find at the outset.

That TED talk is very interesting, Gloucester. Thanks for the link.

A little seed for you: have you heard of the Yoshimoto cube? It is on my list of things to make.

You and I are a good match at this level, Hermes! I also "branched off" in my early resesrches into things. Also had an esrly tendrncy to "connect" things together, look for links betwern ideas.

Think there dhould be a "chst thread" for this sort of thing!

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.

I can only agree with Mr Eames!

Form and function are amongst the more important connections for me. The controls on that shower unit I bought, mirror smooth (apart from one ridge) are a case, for me their form did not connect to their function - to be used by soapy hands. Had I seen that unit set-up in a sales display, rather than a picture on a box, I would have spotted that problem. With the old shower fixed I now have nicely scalloped controls that I can grip easily. To hell with style, give me function every time!

On people, yes, my friend Jane has little knowledge of most forms on engineering, but has a very practical mind and an intuitive understanding as to why things stand up - she argues with builders to get her way and is usually right. It takes only a little encouragement to get her thinking branching out and her confidence building. At nearly 74 she still has more faculties than some younger prople - just never ask her to do maths beyond primary school level!

On things standing up, or not falling down, I can recommend J E Gordon's "Structures: Or Why Things Don't Fall Down"

https://www.amazon.co.uk/Structures-Things-Dont-Fall-Down-ebook/dp/B002XHNNHU/ref=sr_1_1?s=books&ie=UTF8&qid=1500282962&sr=1-1&keywords=Why+things+fall+down

Paperbacks available from a fiver (used) to £100+

Buckminster-Fuller is one of my heroes, for his visionary perception. I have a "tensegrity" model on my toy shelf.

That sort of thing gets my mind fizzing! I assume they used rotating and directional magnetic fields to power, navigate and instruct the bot.

Maybe I am old fashioned and to stuffy but I am putboff by these frenetic presenters with their extreme facial expressions and wave-about hand gestures. But, if it works for the kids I will just quietly ignore it and go for the likes of  Neil deGrasse Tyson , Jim Al-Khalili or even Brian Cox. I especially miss the laid back Richard Feynman

I'm with you Dave. Too much show business does not do anything for my understanding of the subject matter.  In the case of the video I will generously write it off as unbridled enthusiasm for the subject matter, by the presenter. 

There is a You Tube video that shows a young black man who is a teacher, He has a weird hairdo.  He teaches his lessons with a rap music format.  The claim is that it works well for his elementary grade students.  He be jivein' man.  Not my cup of tea but if it works for him and his class.....then go for it.   

The kids can go home or out to the playground and rap the multiplication tables I suppose.

I agree on a personal level, but at the same time believe that anything that will perhaps plant a seed of interest in science in a young mind is useful.

Not my cup of tea. But I'm not a little kid (in age), anymore.
