Student solves a 100-year-old math problem

Divya is a grad student at Penn State.  Her graduate advisor challenged her to solve a problem. There's a supposed optimum solution for a rotator's movement., which was proposed by an aerodynamic engineer in Britain - but which appeared to be incomplete.

After poring over the math and applying some scientific curiosity, she came up with a solution that makes rotation more efficient.  And this finding can be applied to many things, but wind turbines will benefit directly.  

"I created an addendum to Glauert's problem which determines the optimal aerodynamic performance of a wind turbine by solving for the ideal flow conditions for a turbine in order to maximize its power output,"

As always, I remind you to always challenge the paradigm and consider that a theory is based on what we know and is observable - but a theory can always be adapted when we learn more.  

Scientific curiosity for the win! 

Wow! WWII bomb found near Paris

World War II ended 80 years ago, and yet we continue to find explosives and bombs in various locales.  But here is a case where a half ton unexploded bomb was found in a fairly populated area.

They've brought in people to dispose of it, but given its size, location,  and age, it is a delicate operation that may take some time to handle properly.

Its amazing just how much destruction was wrought during that war, and for that matter the Great War that happened 20 years before that.

French Transport Minister Philippe Tabarot said that the huge disruptions were caused by the discovery of a bomb that weighed half a ton. Workers found it overnight while doing earthmoving works near the tracks in the Seine-Saint-Denis region that borders Paris to the north. Bomb disposal experts were called.

Space is hard

Over the last week, we had some space news of note.

SpaceX tried (and failed again!) to launch starship.  The result was similar to the last launch in that they lost control of the upper stage and it pitched uncontrollably and they had to destroy it. 

In this case, the view of the craft and its problem were visible from the east coast of Florida (in spite of the launch from the Texas coastline, it flew eastward).  The reason for the visual was the time of day (sunlight was reflecting at the right angle), the altitude, and the typical trail from the rockets themselves as it pitched.

It was another learning experience for the company, because failure is always an option.  

But it caused problems for airports up and down Florida's coast and triggered a response from the FAA - which undoubtedly will prove "complicated" since Musk dictates what the FAA does and also owns SpaceX (conflict of interest anyone?)

Next up was Intelligent Machines second attempt at a lunar landing.  They launched a few weeks ago, and everything seemed to be going well.  Then when it came time for landing, they had some unexpected thrust from an engine; it landed, but like their last launch, it appears to be not quite upright.  They are getting data back and did deploy the solar panels, so they may be able to salvage some of the mission and meet major objectives.

And finally, we had the other lunar lander that was launched as part of the ride share with Intuitive Machines.  Blue Ghost, from Firefly aerospace, landed successfully and thus becomes the first *successful* moon landing for the US since the Apollo program ended 50 years ago,

  

In their case, I would argue space was hard - but achievable.  We'll learn a lot as they work through their mission objectives.

The good place and its message

I've been watching "The Good Place" which came out a decade ago.  I had never gotten around to it, but I finally decided to give it a go.  Its a lot of fun and deals with some intriguing topics, and includes a Florida-man for some terrific comedy relief.

Anyway, this is worthy of a mention because the underlying premise is that (spoiler if you haven't seen it) the scoring system that sends people to the good place hasn't kept up with our overly complicated world.  You may buy something from a company that doesn't treat its workers fairly, or you don't think about where your product comes from... and that winds up being negative points.

But, there's good from this learning: a theme that emerges is what we do next is more important than what we've done before. We can grow and become better people.

Its uplifting and feels good.  I know the show is from a while ago but there is a lesson in there that becomes even more relevant today.

And that reminds me that the general notion of religion is a bit of nonsense.  Look, if religious belief helps you achieve a form of enlightenment and feels good to you, then I say have at it. 

What I'm talking about is the broad part of religion and a god who wants humanity to succeed. 

How is it that someone like a T-rump (or any of the past "evil doers") can rise to power and make things miserable for the masses, while smart and decent people wind up dying young, having serious diseases, or otherwise have no ability to be that same kind of leader?

There's a flaw in the logic. 

And this is among the reasons that we can’t have nice things

On tariffs

Just a reminder from the university of Nebraska — While the U.S. Constitution grants to Congress the power to levy tariffs on goods, Congress has delegated some of that power to the Executive Branch over time. The U.S. Constitution states in Article I, Section 8 that "The Congress shall have the Power to lay and collect Taxes, Duties, Imposts and Excises." Congress passed general tariff legislation until the early 1930s. However, in a move to grant more flexibility to the President to revitalize global trade in the midst of the Great Depression, Congress gave the Executive Branch the power to negotiate tariff reductions within levels pre-approved by Congress through the Reciprocal Trade Agreement Act of 1934. President Franklin D. Roosevelt became the first President to have the authority to levy tariffs and negotiate bilateral trade agreements without the approval of Congress. The Executive Branch has continued to exercise a level of authority over tariffs over the past few decades. In 1962 President Kennedy signed into law the Trade Expansion Act, which allows the President to adjust tariffs based on threats to national security under section 232.3 This is the authority under which President Trump imposed tariffs on steel and aluminum, which have a vast impact on some of the United States' biggest trading partners and many U.S. industries. Since the beginning of the year, there have been bipartisan efforts in Congress to try to regain some of the power that was delegated to the Executive branch to regulate trade.— 

Our elected officials can't simply allow the sitting president take that responsibility upon himself, hurting relations and impacting everyday Americans
