When Is a Torpedo Is Not a Torpedo?
When it’s a torpedo bat. Last week I looked at baseball’s new torpedo bats in a humourous light. But I did want to take a more serious look, because bat evolution has been part of the tale of baseball since its beginning. Back in the day bats featured long lengths and heavier weights. These days,…

Cannon, Howitzers, Mortars—Oh My!
For the last two days I have been writing about the Fort Pitt Museum and some infographics, environmental graphics, diagrams, and dioramas that help explain the strategic value and thus history behind the peninsula at the confluence of the Allegheny, Monongahela, and Ohio rivers. In particular, we looked at Fort Duquesne, the French attempt to…

Fort Pitt
Yesterday I discussed some of the work at the Fort Pitt Museum in Pittsburgh, Pennsylvania. Specifically we looked at Fort Duquesne, the French fortification that guarded the linchpin of their colonies along the Saint Lawrence Seaway and the Mississippi and Ohio River valleys. In 1753, the royal governor of Virginia dispatched a British colonial military…

Diagramming and Diorama-ing Fort Duquesne
Pittsburgh exists because of the city sits at the confluence of the Allegheny, Monongahela, and Ohio Rivers. As far back as the early 18th century, English and French colonists had recognised the strategic value of the site and as imperial ambitions ramped up, the French finally wrested control of the area from the English and…

Those Quirky Quarks
Last week scientists working at the Large Hadron Collider in Switzerland announced the discovery of new sub-atomic particles: a pentaquark and tetraquarks. This BBC article does a really good job of explaining the role of quarks in the composition of our universe, so I encourage you to read the article. But they also included a…

Black Holes and Revelations: Remastered
Two years ago I posted about how the Event Horizon Telescope Collaboration managed to take the first photograph of a black hole, in particular a supermassive black hole at the centre of the M87 galaxy, one of those galaxies far, far away that we see at a long time ago. This morning, the same group…

Toronto Keeps It Cool
Last month the Washington Post published a nice article that detailed the deep water cooling system that the city of Toronto, Canada uses to keep itself cool. For the unfamiliar, deep water cooling at its simplest means sucking up very cold water from the bottom of a lake or ocean or wherever you can get…

Mt Greylock Cross Section
I spent the better part of the last two weeks travelling and hanging out in the Berkshires and Connecticut River Valley in western Massachusetts. One of the coolest experiences was driving up the automobile route for Mt Greylock, the tallest point in Massachusetts. Most of the drive itself was just regularly spectacular as the mid-morning…

Threats from Little Bodies Inside and Outside
Of course the inside threat are those little bodies of coronavirus causing Covid-19. We cover them a lot here. But there are also threats from little bodies outside, way outside. Like asteroids impacting us. And that was the news yesterday when NASA announced improved data from a mission to the asteroid Bennu allowed it to…

But Where Are the Spiders?
Yesterday I mentioned more about revolutions, well today we’re talking about Mars, a planet that revolves around the Sun. Late last week scientists working with the InSight lander on the Red Planet published their findings. Turns out we need to rethink what we know about Mars. First, the planet is probably much older than Earth.…
