It's hard to find people on TH-cam who properly know their stuff, explain it well and also present it as good as you do. Thanks a bunch for your efforts!
I helped build, test, and Launch the IXPE telescope, which should be announcing some science results & news very soon. I got to see how MSFC builds those nested mirrors. Very Impressive techniques to make those delicate mirrors to the exacting dimensions.
Yep, a PERFECT Christmas story. Paying homage to a water bug we don't mind BOILING ALIVE that has taught us to see further away than we could before. Or is that Easter? Happy Santa day!
Talking about short wavelength optics reminds me of EUV lithography. The optics in those machines are truly magnificent (ha ha ha). Would love to see a video talking about them.
Great presentation, as usual! I was aware of grazing incidence astronomical Xray optics back in the late 80's. The company I worked at did some work diamond turning segments for some telescope project, I can't remember what one as I didn't work directly on it. It's kind of funny how aspects of nature's creatures can inspire technology. I don't know if that is the case here, but the principle is the same. In material science there is effort to exploit the tremendous boost in material properties gained by the proper arrangement of low strength constitutes, as in the case of abalone shell.
A version of this video (and all my other educational ones) without background music is available on my DailyMotion: www.dailymotion.com/video/x891x9x If this video garners enough interest, I will try to convince a former colleague of mine to do a Q&A all about the things I’ve talked about in this video. Please respond to this comment with your questions related to: gamma-ray bursts, high energy astrophysics, x-ray astronomy, lobster eye optics, and the heliosphere.
the gravity waves travelled at the speed of light as it was picked up exactly the same time as the light from the gamma Ray burst? what can this say about both gravity and light? is there anything new to come from that result? merci
To answer your question in short: gravitational waves traveling at light speed rules out many possible advanced theories of gravity and quantum gravity. Therefore, we are more confident about the remaining theories and their parameters being correct. I will cover this in more detail if I am able to do a Q&A video.
@@ImprobableMatter great, look forward to it. I had never thought of it though I can see how the speed of both being identical solidifies a fact for theorising different ideas moving forward. I wonder what else travels at that speed? very interesting stuff cheers
@@forloop7713 The angular resolution is determined by imaging a point source of x-rays (usually at the end of a meters-long beamline) and calculating the angular size on the detector. Then a similar criterion can be applied to this as visible telescopes. I can certainly discuss this at greater length in a future video. Here is a discord link: discord.gg/xsGTSsNmgN
Would we expect an x-ray detector of this type to reveal anything about quasars? Also, excellent video. I wasn't aware of this technology, and I appreciate the clear and succinct explanation. Thank you!
Existing x-ray telescopes such as the Chandra have been used to study quasars already. Since these are point sources in a known location, the lobster eye telescope's advantage in field of view would not help, but they could certainly be used in principle.
Yes. The two upcoming missions showcase the advantages of the lobster eye: scan a relatively large portion of sky in a short amount of time, and with a small size you can pack it with a bunch of other instruments on a small satellite.
I really like your videos friend.. they are really intresting and fun to learn from. I like watching these videos with a hot cup of hot choclate with peppermint :D thank you for making them and have a nice day
Going to the trouble to make such small-scale microchannels is almost certainly not worth it to concentrate sunlight, but macroscopic metal channels (polished) could be an interesting prospect.
Yes, in that case make a large array of square channels of polished metal and taper them so that they get smaller at one end. Maybe try a football/soccer ball type of arrangement of channels that get narrower inwards.
Is there a winner? Genetic research is done in China because noone wants it done in their neighborhood. Tell me, if YOU had to do such research in your community, would YOU build a Viral Research Center next to an open-air market?

No problem, thanks for watching.
Another top of the line video! To the moon!
awesome like always. Looking forward to the next one!
I hope this video takes off, it's very interesting and well produced
Fascinating. Thank you for putting out great content about cool tech!
Than you for placing longer wavelengths on the left and higher frequencies on the right on your graph.
Great vid! Looking forward to more content!

Asianometry has done 2 or 3 videos on the subject, but you can also find some pretty awesome Zeiss videos about their part in the new processes ;)
Man, still on fire, on point!
Gosh, what a good video. Had no idea.

3:35 It probably would have been more efficient to manufacture that grid on the right without all those grey dots at the intersections.
Haha, yes - that is an optical illusion when looking at that kind of grid.

A: how do you determine the angular resolution of such a telescope
B: Does this channel have a discord

No idea how I ended up here, but incredibly interesting!
What mic do you use to record the voice over? (Sounds phenomenal)
Thanks. I use a Blue Yeti.
What else is tickeling your fancy? I bet I'll be pleasantly surprised over the subject matter and it's intricacies.
Great video love me some biomimicry
lovely 😍
Multi-directional solar concentrators with similar technology ?
Going to the trouble to make such small-scale microchannels is almost certainly not worth it to concentrate sunlight, but macroscopic metal channels (polished) could be an interesting prospect.
@@ImprobableMatter I was definitely thinking of something macroscopic, something you can maybe do at home 🙂
Yes, in that case make a large array of square channels of polished metal and taper them so that they get smaller at one end. Maybe try a football/soccer ball type of arrangement of channels that get narrower inwards.
Nice video, but interesting choice of music...
Squids n lobsters 🦑🦞

The lobsters will all die in space!! Why has no one thought of this?!?
Silly me.
All those times I just boiled those lil water bugs alive when I could have been disecting their eyes.
china has won 😔. Great new channel, though.
