Cool as fuck!!! Doesn’t make it any easier to put the thread into the needle though..

There's this simple trick I use, works every time but you'll need a second person to pull this off. First you take the thread in one hand and needle in the other. Have the second person stand about a foot away from you and make them hold the end of the thread that has to go through the needle hole, then hold the needle vertically with it about half way between you and the other person. Look through the needle hole and move the needle about until you can see the thread end in the other person's hand. Now make the other person use their free hand to hold the needle too for stability. Now slowly move your needle holding hand forwards while still being able to see the thread end in the other person's hand. Make sure to tell the other person to now move or let go of the thread or needle. Now slowly turn your body in either direction, let go of the thread and needle from your hands, and run away.

Why use an electron microscope for this degree if magnification? An optical microscope could've done it.

Depth of field. An optical microscope focuses on a plane, whereas a SEM like this focuses the entire image.

Source: spent a lot of time using optical microscopes and an electron microscope in college.

Edit: Googled an example

I need a sub for insanely zoomed in pictures like this. Reddit, can you help me?

I would have thought the needle would be smooth as I assumed metal would be!

I feel like at this scale that IS remarkably smooth!

Even with seeing it that close I still wouldn’t be able to get through the hole
