Here’s a handy soldering tip from John Powell of JP Aerospace.
First time writer Veatrice Chapin sends us on an adventure of hardship and triumph. Set in mid-19th century England and Australia. Young girl is sent to prison for murder, and must escape, though it means certain death. I found the book constantly engaging.
Did a bolide explode over Sodom and Gomorrah? Some say, yes. Opposing view given in able fashion by Scott Manley.
Antov Petrov gives another stellar performance with a possible explanation for the story of Sodom and Gomorrah.
This is a foundational YouTube video, because you can use checklists for travel planning and execution, going to the grocery store, planning a cookout or any gathering of friends and family. I found the checklist my friend when I was flying. I kept my checklist system on my knee throughout the flight, but it has general uses as well.
Oh how far we’ve come. But stay alert, because change is happening through even our very cell phones. Thanks again to Joe Scott for this informative and surprising walk through my great grandparents’ era.
Testing in his nearly Mach 4 wind tunnel, JP beats the cost of using an SR-71. The tests take place in a 40 foot long warehouse, part of the research on space-flying ascender series airships. Airships to space? Can do, although it is down the road a bit on the long road of experiment after experiment.
A better look at the mathematics that determined the cosmological constant reveals a better way to grok the averaging that gave us the constant in the first place. And, we exist in a thinly populated region of the universe. And to top it off, our local Hubble constant should be updated to reflect density as observed locally. Sabine Hossenfelder, you rock!!!
Amazing load of facts about the whole prep, launch and recovery experience. And most interesting to me was the Hazel project that was lost in obscure bids when the SR-71 won the go-ahead. The Hazel proposal broke the rules of physics then supposed in the intuition of many scientists. Why did the SR-71 Blackbird win the bidding? Ask Lockheed. They are often in the know about large US government contracts. What exactly happened way back when? Thank our lucky stars for SpaceX crowding into the competitive field. I pray JP Aerospace can make sense of the Hazel proposal, and construct a Hazel prototype to learn from. It should prove exciting, and eye opening.
A rounded nose, and elliptical cross section for the wings, once internal structural improvements are installed. This is currently the smallest airworthy ascender at about 26 feet in length.
