Sciency Words: Newtonmas

Hello, friends!  Welcome to Sciency Words, a special series here on Planet Pailly where we talk about science or science-related terms.  In today’s episode, we’re talking about:


Newtonmas is often described as a secular alternative to Christmas.  Some people see Newtonmas as an affront to Christmas and all things Christian.  Me?  I don’t believe science and religion necessarily need to be adversaries, and I don’t see any reason why we can’t celebrate two things on the same day.

Newtonmas commemorates the fact that Isaac Newton was born on Christmas Day, 1642.  Or at least that’s Newton’s birthday according to the Julian calendar.  According to the Gregorian calendar, Newton was born on January 4, 1643.

If I may wander into the calendar technicality weeds for a moment, the Gregorian calendar was first introduced in 1582, but it was not adopted by all countries right away.  Great Britain didn’t switch over until 1752.  And so at the time of Newton’s birth (1642/1643), in the place where he was born (Lincolnshire, England), the Julian calendar was still in effect, and it remained in effect for Newton’s entire lifetime.  So as far as Newton and his countrymen were concerned, he was born on December 25, 1642.

The first documented celebration of Newtonmas occurred in Japan.  In the late 1800’s, a small group of students at the Imperial University in Tokyo formed an Isaac Newton fan club.  This fan club rapidly grew in popularity and soon included a mix of undergrads, grad students, and professors.

And so on Christmas Day, 1890 (Gregorian calendar), members of this Newton fan club got together for the first ever Netwonmas party.  According to this article from the time, the party included humorous science lectures, a science-themed gift lottery, and plenty of “laughter and good cheer.”  Basically, Newtonmas started out as nerdy fun.  And as far as I’m concerned, that’s what it still is (and I do not want to hear any “war of Christmas” nonsense in the comments, thank you very much).

So merry Newtonmas, friends!  And merry Christmas, too!  There’s no reason you can’t celebrate both, if you want to.

P.S.: This will be my final blog post of 2020.  I’m taking some time off for the holidays.  I’ll see you again, friends, on January 6, 2021 (Gregorian calendar) for the first IWSG post of the New Year.

Inverted Space (Tomorrow News Network: A to Z)

Hello, friends, and welcome back to the A to Z Challenge.  For this year’s challenge, I’ve been telling you more about the universe of Tomorrow News Network, my upcoming Sci-Fi Adventure series.  In today’s post, I is for:


On ancient Earth, there were three great revolutions in physics.  First came Isaac Newton and his laws of classical mechanics.  Then came Albert Einstein with his theories of special and general relativity.  And lastly, near the end of the 21st Century, Dr. Harold Strickland published his theory of inverted space.

In the simplest possible terms, inverted space is a place where the laws of physics are reversed.  It’s a universe of anti-physics, if you will.  Dr. Strickland believed that in order for our universe to exist as it does with the laws of physics that it has, then an equal and opposite universe must also exist to create balance.

One might expect such a radical and bold theory to spark debate and controversy among the scientific community.  It did not.  Few took any notice of Strickland’s work at the time.  It wasn’t until many years after Strickland’s death that he received the recognition and credit he deserved.  What changed?  The discovery of faster-than-light technology.

You see in our universe, nothing can travel faster than the speed of light; in inverted space, nothing can travel slower than light.  Of course, jumping into inverted space is dangerous.  The laws of physics are reversed, after all.  The attractive forces that hold atoms and molecules together become repulsive forces.  Molecular and atomic decoherence can occur within seconds!

But a quick jump in and out of inverted space is relatively safe, and a sequence of quick, carefully calculated “inversions” can allow a spacecraft to cross the vast distances of the galaxy.

It’s also worth noting that in inverted space, time runs backwards instead of forwards.  This troubled Dr. Strickland, yet it was an unavoidable consequence of his math.  If you were to jump through inverted space and then jump back to your starting location, would you not arrive before you departed?  Would this not violate causality and create a time travel paradox?

As it turned out, nature has its own ways of preventing paradoxes, even if Dr. Strickland couldn’t find them in his math.  When you push two magnets together, either positive to positive or negative to negative, the magnets resist.  They repel each other, and the harder you try to push them together, the harder they push back.

Something similar occurs in inverted space.  If you jump through inverted space and then attempt to jump back to your original location, your spacecraft will be deflected off course.  Your past and present selves seem to repel each other, like magnets, and so this is known as the chronomagnetic effect.

Nothing in the theory of inverted space predicted this chronomagnetic effect would exist, and nothing about the theory of inverted space can help explain why it occurs.  So while inversion theory is more advanced than relativity theory or classical mechanics, it still does not provide a complete picture of how the universe works.

For a complete picture of how the universe works, you’d have to learn about chronotheory, the science of time travel.  And next time on Tomorrow News Network: A to Z, we’ll talk about the people who use chronotheory to bring you tomorrow’s news today.

Sciency Words: The Anomalous Precession of the Perihelion of Mercury

If you’re anything like me, you’ve probably looked at planetary orbits and asked yourself: why does Mercury’s perihelion precess so anomalously? That simple, straightforward question is the subject of this week’s edition of Sciency Words.

Sciency Words is a special series here on Planet Pailly where we take a look at a new and interesting scientific term so we can all expand our scientific vocabularies together. Today’s term is:


I know, it’s a bit of a mouthful, but trust me… this anomalous precession thing is pretty cool.

Gravity According to Newton

Back in the 17th Century, Isaac Newton found a mathematical way to describe gravity, and his mathematical description worked for everything from falling apples to the orbits of all the planets. Well, all the planets except Mercury.

Mercury’s perihelion (the point where Mercury is as close to the Sun as it gets) moves.  That in and of itself isn’t so strange, but the perihelion moves a tiny bit faster than it should according to Newton.
Mercury’s perihelion (the point where Mercury is as close to the Sun as it gets) moves. That in and of itself isn’t so strange, but the perihelion moves a tiny bit faster than it should according to Newton.

The mystery of Mercury’s orbit (or the “anomalous precession of the perihelion of Mercury,” to use the technical lingo) baffled scientists for centuries. That is until Albert Einstein came along.

Gravity According to Einstein

Einstein’s theory of general relativity postulates that space and time are not separate entities but two aspects of what physicists now call space-time. General relativity predicts that the force of gravity causes space-time to bend or warp.

Needless to say, the Sun has a lot of gravity. Turns out that the warping of space-time around the Sun precisely explains Mercury’s weird orbit. In fact, every planet experiences some degree of this anomalous perihelion thing. It’s just that, because Mercury is so much closer to the Sun, the warping effect is significantly more noticeable.

This is perhaps the planet Mercury’s greatest contribution to science. The anomalous precession of Mercury’s perihelion provided one of the earliest proofs that general relativity—and all the wibbly-wobbly, timey-wimey stuff that comes with it—is not just science fiction.

Artsy Science: Newton’s Waste Book

Artsy ScienceToday’s post is part of a collection of posts on the artistic side of science.  Through both art and science, we humans try to make sense of the world around us, and the two fields have a lot more in common than you might expect.

* * *

It’s the 17th Century.  Paper costs a small fortune, and young Isaac Newton receives a valuable gift from his recently diseased stepfather: a notebook.  Only the first few pages have been used.  The rest are blank.  So what does young Isaac decide to do with this precious treasure?

The prudent choice would be to save it for something important.  Perhaps some groundbreaking discovery that would have changed the way we view the whole world.  Instead, the idiot named this notebook “the waste book” and wasted it on trivial nonsense.

Newton filled his waste book with information about art, music, alchemy, mathematics, theology, science, philosophy… pretty much anything.  The book’s contents were so random and disorderly that, following Newton’s death in 1727, the book was marked “not fit to be printed.”

But in that mess of scribbly handwriting, we can find the first hints of Newton’s genius and the profound discoveries he was about to make.  By not treating paper as something sacred, he allowed himself to play with new ideas.  Perhaps he named his notebook the waste book to remind himself that the pages were to be “wasted” even on thoughts that might at first seem silly.

Isaac Newton

So the next time you sit down with a blank piece of paper, waste it on some trivial nonsense.  You have no excuse not to.  Paper is a lot cheaper today than in Newton’s time.  And if you waste enough paper, maybe… just maybe… you’ll stumble upon an idea that will change the world.

P.S.: It may not be fit for printing, but the waste book is available to the public for free online.  Good luck reading Newton’s handwriting, though.
