    Yes to scale bars! There is no reason they should be any more obtrusive than the organism name(s) and magnification that you already show.

    The saddest thing I had to leave when we moved recently was the baby pool converted to a frog & dragonfly habitat. Got my grandson a cheap microscope & we looked at all manner of cool stuff. I've been known to teach anatomy with roadkill too. NOT your average grandma. Love sharing this channel with him, he also likes composing on his IPAD. Never stop being you!

    Thanks for this awesome channel. Can I make a request? I like to see the ameba pluricellular forms. Pluricellular forms happen when in areas nutrient depleted many amebas join in a worm form to travel far and change to a tree-flower form. The ameba is multicellular life form too ;D . Also I have another. Do you choice do not use inks in the samples but I think in some cases, flagela or cilia, we lost a wonderful show to see. The flagela alwas look invisible. Thank you.

    I would suggest that this channel, try to break down what makes each cell special. We all know text book images of cells. However, i can't really tell the difference between a mitochondria from a nucleus in any of these cells.

    I am curious why you chose to use flat slides instead of depression slides for this though?

  • Matthew Morycinski

    If standard lens were used, the magnification would be true for screen diagonal of roughly 10 inches (254 mm). But that would likely show image as a circle, as well as distortion at the edges. I venture a guess that about 70mm equivalent lens is being used. Therefore the image on which the magnification would work out true would be the size of a large cell phone screen - 7" diagonal.

    Now, suddenly there is a need for an automatic microscope that can identify and track an object as it moves around the slide surface, automatically adjusting the focus to always keep the object in view. I'll start working on that...

    First of all a wonderful video I have a question though, are the magnification notes you provide just the magnification written on the objective or do you include the magnification of the occular lens as well? I am taking a microbiology course at the moment and our microscopy professor always emphasizes the effect of the occular lens on the magnification. He also said some people include it and some people don't so i am very curious about the way you do it.

  • Joe Salizanikop

    If you don't use stains because it's potentially harmful to them, do you place them back in the containers they came from? Do they live on the slides now?

  • Allen Johnson
    Allen Johnson Day ago

    Perhaps a good way to show an in-image size comparison would be to place a distortion test target below the slide. Some, like the SL1 from JD Photo Data have grids down to 10µm in size. If something like this proves difficult to have in focus along with the specimen, then it can be used to measure the pixels between the gridlines at each magnification level in order to add a digital scale bar in post production.

    Fucking awesome. Is all I can say, like this channel blows my fuckin mind and hanks voice is so soothing, been a massive of fan of sci show, my mum is a microbiologist and shes amazed how much shit i can talk about stuff she'd never thought i'd ever know about hahah! I ran bars for years, now I run a car customs shop, but this stuff is fucking phenomenal. Science is fucking so awesome.

  • Nicolás Ordenes

    Those shots of the jars (1:30 and 2:18 ) were wonderful, loved the resulting blend of light temperature, glass tints and samples. I was hoping to see a more detailed review of the microscopes though, specially the telescope that James built. After seeing the footage of James taking samples I thought that I would love to see a vlog style videos of samples recollection. First talking about were will the samples be taken and what to expect, then taking the first look at the microscope to see what was found and ending with how would it be stored and feed. Of course, if you're comfortable with shooting outside and being protagonist.
