The colors are added in, of course, with it being an electron microscope image. Another picture:
Its crazy how crude all of our tools look at this magnification.
Some medical tools look crude even at regular size… they don’t call orthopedics bone carpenters for nothing!
People would never set foot in a hospital again if they found out how many orthopedic surgeries involve a dewalt drill at some point.
I’m just going to leave this discovery here.
That’s great. I rotated through an ortho lab in the 1990s, and the joint replacement kits back then included a sterile, disposable drill that you were just supposed to throw out after the procedure.
I recently saw a knee replacement that used one of those ryobi oscillating cutters (the ones that were super trendy a few years back). Total garbage for home use, but man with a 3D printed cutting guide shaped to fit over the bone, they finished the osteo and arthroplasty portions in ten minutes flat. Just insane what we can accomplish when we combine modern volumetric imaging techniques with coupons for home depot.
My knee replacement was carried out with an epidural pain block, plus sedation. I came down from cloud nine briefly to wonder why someone was doing renovations while surgery was in progress - then realised all the drilling and hammering was my new joint going in. Phew! Back to lala land…
Lmao “oh shit I’m a house”
I gained an appreciation for how precise/sharp our tools are when I learned microtomy. If you so much as touch the cutting edge with anything outside of its intended use it messes up that area of the blade instantly. Same goes for a nice pair of chef’s knives.
See that little hook at the point? This is from penetrating skin ONCE.
This is why you don’t re-use needles folks!
There are other reasons.
This is fascinating. I mean we all know the theory, but to actually see the cells under magnification puts you in range, and makes you wonder what else there is to know. And the answer is always MORE.
Education should work more practical application in with the theory. I’m looking at you, calculus!
Seriously. I’m in my 40s and this is the first time I’ve ever had any sense of scale for red blood cells. Very cool!
But it’s hard to perceive the scale of the needle tip itself, so there’s no good reference object for the scale. They should have included banana or something for the comparison.
The scale of the micro verse is wilder than you realize
100 points for the video with both of those objects :)
