    Thank you, Dr. Jones! I have been to the telescopes as well and it is indeed a remarkable experience. We took the “saddle road” between volcanoes on the way from Kona to Hilo and stopped several times along the way on side roads to experience the Martian-like landscape as well. Highly recommended if you go to the island of Hawaii to make this trip if your rental car has 4WD low. We went from 80+ degrees in Kona to 30 degrees on top of the volcano in a couple hours and it was snowing lightly up there. Hard to imagine that the temperature changes that much from paradise to nowhere but it surely does! Appreciate another great video as always.

      How neat that you have visited there too! Would certainly be perfect thing to do on a Kona to Hilo drive or vice versa. You had a much more extreme temperature change than we did - I'm envious that you got to experience it actually snowing on Hawaii. Have you been to Haleakala on Maui? Its even more Martian-like and much more beautiful from a photography standpoint?

      @@ElectromagneticVideos I have not been to Haleakala yet, but on the next trip for sure. The side roads off the saddle road were amazing - one of the most surreal experiences I have ever had; we were above the clouds on a desolate moonscape. Aside from Grateful Dead concerts, it was psychedelic. LOL Glad you had a great experience there and thank you for sharing. Looking forward to your upcoming videos.

    I visited Haleakalā (10k feet) on Maui a few years back for a sunrise. Definitely damn cold which was exacerbated by the wind. If I recall correctly, the temperature difference between dark/sunny was huge. They warn you about the cold, but they fail to warn about the wind...so be prepared if you ever do this. Definitely cool watching the sunrise from above the clouds!

    • @ElectromagneticVideos
      @ElectromagneticVideos  11 месяцев назад +1

      I was never lucky enough to see the sunrise from up there - must have been great! Were you able to see stars and the Milky Way before sunrise? I have always thought it must be magnificent from up there.
      Interesting point about the darkness and cold. I remember how quickly things cooled during the 2017 eclipse - the sun's radiant energy hitting the ground has a much more immediate effect on warmth that we generally give it credit for.
      Wind - I wonder of at dawn the winds on the mountaintops in Hawaii are partly due to the temperature change? Even during the day on Mauna Kea there was a lot of wind - a jacket or windbreaker is certainly a must!

      @@ElectromagneticVideos The only thing I could think of before the sunrise was how cold I was. I didn't think to look up! Lol.
      It did get warmer rather quickly once the sun was above the clouds. I believe the winds also subsided a bit. However, it was probably 10 years ago and a little fuzzy in my mind.

      Glad you liked it! My PhD was on 3 dimensional optics and image processing The R&D group I worked with back then did mostly astronomical image processing and some early work on Adaptive Optics which is why I was so pleased to see Adaptive Optics being used in the Keck and elsewhere - always fascinated me!. I'm and Electrical Engineer / Computer Engineer who does a lot of stuff on physics side of things as well. If you look at some of my other videos you will see things from all those areas of science and engineering!

      Glad you enjoyed it Peter! Isn't it amazing see the rings of Saturn with your own eyes? As a kid I was fascinated by astronomy. I have a small telescope I bought years ago - first thing I pointed it too. What always amazed me is how much astronomers and scientists have managed to figure out from astronomical observations that until recently were just points of light. Seeing the magnificent engineering of the telescopes sure made me envious of the people working on those technologies.

    Thanks for letting us see such a quirky place!
    The highest I've been is Zermatt, Switzerland.
    Famous for the Matterhorn mountain that can be seen on the Toblerone chocolate.
    I had feelings of altitude sickness there, which was very unpleasant!

    • @ElectromagneticVideos
      @ElectromagneticVideos  11 месяцев назад

      I never thought of it as quirky - but it certainly is different! Its interesting that you experienced altitude sickness too. I can imagine how it could be very unpleasant after a longer period of time. I gather you can acclimatize to it by spending a few days at higher and higher altitudes. I find it amazing to think that the constructions workers were able to acclimatize to the point of being able to do significant physical activity at that altitude to build the telescopes.

      I use Google translate, although I don't need to, mostly to get the words in the right order, maybe quirky was the wrong word?
      I mean a place that suits us tech-savvy geeks…
      Yes, you may need to acclimatise, you got up very quickly and didn't give your body a chance to find a balance!
      Both our bodies and machines need to adapt to the lower air pressure, maybe you had other equipment with you that doesn't like the height, like a laptop or something?

    Nice. Was curious how they corrected the images, Brakes got me thinking about the tires, Apparently there would have been an effective increase of ~7PSI at 14000 feet

    • @ElectromagneticVideos
      @ElectromagneticVideos  11 месяцев назад

      Thats and interesting point - never thought about the tire pressure being effectively higher. I guess if a vehicle was spending most of its time up there, the thing to do would be to adjust the tire pressure down by the appropriate amount for more even tire wear and better traction. I wonder if they adjust the tire pressure on the giant equipment used to haul huge telescope parts up there when constructing the facilities.

    Very interesting. Thank you. I was in Hawaii many years ago, but we stayed on Maui. We did go up to Haleakala which goes up to about 10,000 ft. that was quite spectacular. Sadly, no telescope visits.
    The keck is an amazing observatory, the adaptive optics is incredible. I knew about the laser, but did not know how it worked until now. I also found the interferometer to be quite incredible. It is definitely something I'd love to visit, but not likely. Take care ⭐🌟⭐

    • @ElectromagneticVideos
      @ElectromagneticVideos  11 месяцев назад +1

      Your welcome! Haleakala is beautiful up top! Keck - yes - amazing - and the interferometer with the two Keck telescopes is something! I purposely kept all of that stuff short - hopefully just enough to give a general audience an appreciation of what is going on. When I was a grad student the lab I was in was very involved in astronomical image processing and early adaptive optics work. It wasn't my topic of research (3-D imaging and processing) but I was always fascinated but it and I learned a lot about it - it was wonderful to see adaptive optics have pretty much become part of modern telescope design nowadays.

    OK!! Mauna Kea is the best in the world location for a giant telescope. The question not being asked is HOW MUCH will it benefit the people of the Big Island of Hawaii MONEY wise??? Not free visits but money wise??

    • @ElectromagneticVideos
      @ElectromagneticVideos  7 дней назад

      I think thats question that applies to any sort facility, be it scientific as in this case, tourist resorts, military bases, factories, airports etc.
      I do know that each of the telescopes has a significant number of staff and students stationed around the 10000 foot level as well as offices and facilitates in the towns at ground level. And employees ranging from janitors and contractors to administrators and scientists and engineers. Most of the telescopes are funded from off-island universities and research establishments in mainland US or internationally. so significant amounts of external money ends up paying the salaries of those big island residents and in turn gets recycled when they pay for goods and services locally. How much does that all bring in - and how does that compare to other types of facilities of business? I dont know - I'm sure somebody in the Hawaiian state government or University of Hawaii has the numbers.
