A couple of weeks ago, I posted an #animation of a point on a circle generating a #cycloid.
Generating a cycloid

If you turn the curve "upside down", you get the #BrachistochroneCurve. This curve provides the shortest travel time starting from one cusp to any other point on the curve for a ball rolling under uniform #gravity. It is always faster than the straight-line travel time. This is an interesting problem in #ClassicalMechanics and exercised luminaries like #Newton and #Euler. I think the latter's use of the #CalculusOfVariations is a stroke of genius.

Anyway, the #animation took a bit of thought as it requires a bit of #Mechanics, some #Integration and is made a bit more tricky as the curve is multi-valued and so you need to treat different branches separately. The #AnimatedGif was produce with #WxMaxima.

For some reason that I can't fathom, I'm not finding it possible to upload the graphic and so if you want to see it, please use the link below.

Sign the petition! Holmdel Township Committee, Monmouth County Board of Freeholders, NJ State Legislature: Save Big Bang Antenna

I just signed a petition to preserve the Holmdel Horn Antenna, a National Historic Landmark used by two Bell Labs Nobel Prize winners to confirm the Big Bang Theory of the creation of the universe.

Please join me and sign this important petition as well.

Friend,

I signed a petition on Action Network telling Holmdel Township Committee, Monmouth County Board of Freeholders, NJ State Legislature to Save Big Bang Antenna.

The historic Horn Antenna, which confirmed the “Big Bang Theory” of cosmology, sits on 42 beautiful acres of Holmdel Township named Crawford Hill. The location is the highest point in Monmouth County. The antenna and land are being endangered to become a high-density residential development of 100-200 townhomes.

Concerned Citizens for Informed Land Use (CILU), Friends of Holmdel Open Space (FHOS) and Preserve Holmdel (PH) say NO to developing the property and moving the Horn Antenna.
We say YES, to keeping the Horn Antenna and the property it sits on being PRESERVED IN PERPETUITY AS A PUBLIC PARK.

Please sign our petition urging the Holmdel Township Committee, the Monmouth County Board of Freeholders, and our legislators to preserve the Horn Antenna and Crawford Hill.

Can you join me and take action? Click here: https://actionnetwork.org/petitions/save-big-bang-antenna?source=email&

Thanks!

What do #billionaires & trillionaires want, lack & #money can't buy? #Time.

#Human lifespan hasn't changed significantly in 2,000 years. Life #expectancy has risen, but not #lifespan.

How can a human #live forever? #Elites have been asking this for millenia. The #answer has been here for 75 years. #Spacetime compression changes the relative rate of time.

Spacetime is #elastic. It is compressed by mass & decompressed between #mass in #nature. This effect can be achieved artificially, hence #CERN & the focus on #quantum #gravity & #energy efficiency.

By changing compression of a volume of spacetime relative to background spacetime, time dilation is achieved & life effectively extended until #scientific #advancement cures #death. This is what #elites are funding.
