“The First Knot”, woodcut by Albrecht Dürer, c. 1507, design taken from an engraving by the school of Leonardo da Vinci. On the right I colored strands to better understand the design. The blue portion by itself is the unknot, while the red portion is the (16, 3) torus knot ,,,

FLASHBACK: Ten years ago tonight, Hillary Clinton said that Donald Trump would operate as a puppet of Vladimir Putin. Hillary was right about everything.

Elon Musk and StarLink have played an important part in Ukraine's successful resistance against Russia. As a supporter of Ukraine I thank @elonmusk for that.

First. The narrative that diesel prices in America are heavily impacted by Ukrainian attacks on Russian oil refineries is completely fabricated. ​Second. The sanctions waiver Trump just granted to Russia is using the fabricated narrative above to make it look like it's in America's national interest. It is not. ​Third. It was planned, and the narrative was constructed to make it happen, which took time. Fourth. This offers Russia's economy a necessary lifeline it desperately needs. ​Fifth. this is happening during one of the largest Russian bombing campaigns targeting the civilian population of Ukraine, and right before winter, a season the Russians proudly and loudly plan to make the hardest and deadliest for Ukraine yet by bombing our civilian infrastructure and causing a humanitarian disaster. ​This is well planned and played. A masterclass in betrayal, executed at the hardest possible time. I can almost feel a physical knife between my shoulder blades...

In the 22nd month of Biden's presidency the Dow was rebounding after Russia's invasion of Ukraine (if memory serves). The Dow's performance under Trump has been about the same as Biden's. We did better under Obama. Obama and Biden did not support Ukraine as strongly as we should have. But they were not outright Russian assets.

This is a beautiful presentation. L1/L2 are gravitational waypoints into and out of cislunar space, the Moon gives up to 1 km/s of 'free dV' and cyclers can transfer resources into lower orbits.
The panel discussion was great. Here is a video I showed as part of my talk before-hand. Thank you Shane (@RossDynamicsLab ) for generating the video. It clearly explains how asteroid material brought to the Rim (SEL-1 or SEL-2 for example) can be distributed throughout Cislunar space.

Excellent vid. Learned a new term - "Warden Line" One of my imagined ZRVTO linked tethers resides at the Warden Line. This tether throws payloads to an apogee corresponding to what they call the "MacLane Torus" where it can enter the Lunar Hill Sphere. And I regard the Lunar Hill Sphere as a bay that opens our neighborhood to the solar system.
This is a fantastic video explaining orbital dynamics and the resulting economics, and security considerations of cislunar space. Well worth the 8.5 minutes to watch. youtu.be/kdpOdSMzXTA?is=By6z…

Ukrainian latitudes lie between 44º and 53º. Siberia is 50º to 77º latitude. It is very vulnerable to General Winter. Ukraine has already demonstrated they can reach the Yamala-Nenets infrastructure. If Putin tries again to freeze Ukraine the retaliation will be devastating for the Russian people. Putin needs to fall out of an upper story window sooner, not later.

泽连斯基最新爆料:8000朝鲜兵已在俄罗斯本土,另1万正在训练中。 俄罗斯怎么付账?直接帮朝鲜建沙赫德无人机工厂。 这已经不是俄乌战争了,这是俄朝联军。以后朝鲜的无人机可能就飞在首尔和东京上空了。 还觉得离我们很远吗?

Here I asked @grok to put a mass at the Mars Phobos L1 point and the tether extending 3.2 km past the MPL1 point. I believe this is the minimum tether needed to stay aloft and not fall back to Phobos. This tether would allow ships to dock with the tether and descend to Phobos without kicking up the debris and dust clouds that rocket landings on Phobos would kick up.

I asked Grok to draw a tether extending from Phobos' near point towards Mars.

And I have been blocked from this thread. I believe by @hookskat. I provide citations backing up my claims. These people are not merely incompetent. They are willfully trying to suppress information harmful to their narrative.
This is a lie. I'll allow you to correct the statement to something closer to the truth by removing the word "only" from your post. Newton was a brilliant Christian crackpot who believed in alchemy and created calculus essentially on a dare. It doesn't have to be so binary.

Paul Warburg casually mentioned his time in seminary: youtube.com/watch?v=lR9kWRha… I was pleasantly surprised. Warburg's techno savvy and very pragmatic. I would not have thought he was a Baptist pastor. I agree with the thrust of this video. Public perception is key. For example The War of Northern Agression vs The Emancipation of The Slaves. I remain optimistic Ukraine will prevail.

How about calling on Putin to stop killing Ukrainian civilians
Trump: "Zelenskyy has to do one thing -- he has to stop knocking out diesel fuel in Russia. He's causing a shortage of diesel fuel. This isn't done by the Middle East, this is done by what's happening with Russia and Ukraine."

I seem to recall Elon making the correct prediction that the next conflicts would be drone wars. Paul Warburg just did a video on China and possible robot soldiers: youtube.com/watch?v=D7PuGzvv… Warburg opines that human robots are mostly for show and that the more useful robots will bear no resemblance to humans. I've heard similar arguments in science fiction forums. Although (in my opinion) humanoid robots may be more useful for general purpose uses than the robots designed for very specific tasks.

THIS ISN’T GETTING ENOUGH ATTENTION 🚨 During a heated Senate hearing, Mark Kelly pushed back after Tommy Tuberville said, "There's nobody more military up here than me” — respectfully, yet forcefully: “Senator Tuberville, you just said, ‘There's nobody more military up here than me.’ As far as I can tell, there are four senators in this room that served in the US military. In some cases, for decades. Three of us combat veterans. You say it a lot. But you've never served. So I take great exception to you saying that.” Sen. Kelly has the backbone Senate Republicans do not. I can’t wait for him to be president someday. I hope he wants that, too!
