Allies Of The Truth

Together, united in the purpose to do our jobs under the Constitution, without regard to party or party loyalty, let us resolve to be allies of the truth -- and not partners in its destruction.

Wow Much Coin How Money So Crypto

It says a lot about the state of the cryptocurrency space in general that a currency with a dog on it which hasn't released a software update in over 2 years has a $1B+ market cap.

Water Ice Cliffs On Mars

Thick deposits cover broad regions of the Martian mid-latitudes with a smooth mantle; erosion in these regions creates scarps that expose the internal structure of the mantle.  We investigated eight of these locations and found that they expose deposits of water ice that can be >100 meters thick, extending downward from depths as shallow as 1 to 2 meters below the surface.  The scarps are actively retreating because of sublimation of the exposed water ice.  The ice deposits likely originated as snowfall during Mars' high-obliquity periods and have now compacted into massive, fractured, and layered ice.  We expect the vertical structure of Martian ice-rich deposits to preserve a record of ice deposition and past climate.

One Must Improvise

To succeed, planning alone is insufficient.  One must improvise as well.

[T]hroughout my life, my two greatest assets have been mental stability and being, like, really smart. ...  I went from VERY successful businessman, to top T.V. Star to President of the United States (on my first try).  I think that would qualify as not smart, but genius....and a very stable genius at that!

50th Known Mersenne Prime Found!

January 3, 2018 -- Persistence pays off.  Jonathan Pace, a GIMPS volunteer for over 14 years, discovered the 50th known Mersenne prime, 277,232,917-1 on December 26, 2017.  The prime number is calculated by multiplying together 77,232,917 twos, and then subtracting one.  It weighs in at 23,249,425 digits, becoming the largest prime number known to mankind.  It bests the previous record prime, also discovered by GIMPS, by 910,807 digits.

Just how big is a 23,249,425 digit number?  It's huge!!  Big enough to fill an entire shelf of books totalling 9,000 pages!  If every second you were to write five digits to an inch then 54 days later you'd have a number stretching over 73 miles (118 km) -- almost 3 miles (5 km) longer than the previous record prime.

We Live In The Future

We live in the future: car features being brainstormed in real time on a global social network, over Christmas, to be implemented the next quarter.
