Artist Stephen Lund Rides His Bike to Create GPS Doodles

Strava is a popular GPS program used by runners and cyclists to track their workouts. Victoria, British Columbia-based artist Stephen Lund uses the program to create these “GPS Doodles” instead. Pedalling an average of 70 kilometres in a single day for each design, Lund completed 70 doodles last year! #Love it!

Fandom GPS

No but imagine one where you could alternate fandoms each day;

Supernatural Fandom GPS Day:

Bobby: “Ya, idjit, go another half mile and turn back around.”
Castiel: “I don’t understand. There is a store called ‘Winchester Gear’? What do they sell? Salt shotgun shells?”
Crowley: “I run Hell and I don’t even want to go to this place. Why exactly do you want directions there?”

Harry Potter Fandom GPS Day:

Snape: “Take exit three hundred and ninety four.”
McGonagall: “Turn left now, you babbling, bumbling baboon.”
Luna: “If you look out your window more often, you’re much more likely to spot a Crumple-Horned Snorkack.”

Sherlock Fandom GPS Day:

Mycroft: “If you could manage it, a left turn this century wouldn’t be your worst decision ever.”
Mrs. Hudson: “I’m not even your landlady, dear, but if you want my directions, you’ll go back home and have a nice cuppa.”
Lestrade: “Right, what you want to do here is look out for the lane changes, because the traffic can be murder.”

Doctor Who Fandom GPS Day:

Amy Pond: “Ya bloody idiot, what ya wanna go that way for?”
River Song: “Oh, are we going somewhere? How exciting!”
Clara Oswald: “Drive. Drive you clever human. And remember to always wear your seatbelt.”

Lord of the Rings Fandom GPS Day:

Legolas: “My elf eyes see that you’ll need to turn west in 3 miles.”
Gimli: “Increase speed when you get off the interchange. Nobody cuts off a dwarf!”
Gollum: “Turn right here, Precious. Yes, right here! Gollum!

Marvel Fandom GPS Day:

Nick Fury: “I recognize that you missed the turn, but given that it was an important turn, I’m going to need to recalculate now.”
Loki: “You missed the turn. Well, I’m not exactly shocked. You must not be truly desperate to reach your destination.”
JARVIS: “May I say how refreshing it is to finally see you on the right course?”


Science Spotlight: How Your Smartphone Knows Where You Are

In 1978, the United States launched its first operational GPS satellite and by 1993, 24 GPS satellites were orbiting Earth, completing the NAVSTAR GPS constellation. Each satellite weighs around 1,900 pounds — the size of a large automobile — and orbits the earth every 12 hours in a formation that ensures every location will be in direct radio contact with at least four satellites.

Dressed with Skill

Neuroscientist May-Britt Moser, whose birthday is this month, gained global recognition in 2014. She and her then-husband Edvard won the Nobel prize in Physiology or Medicine for their work on the brain’s “inner GPS”. They discovered a type of cell, called a grid cell. They found that when a rat passed certain points arranged in a hexagonal grid in space, nerve cells were activated that form a kind of coordinate system for navigation. They went on to demonstrate how these different cell types co-operate. May-Britt chose to wear an extraordinary dress for the Nobel ceremony. Designed by Matthew Hubble, this depicted the cells on which Moser has focussed her scientific attention. The idea echoes the Nobel Textiles scheme from the MRC-CSC. This brought together artists at the Central St Martins college of art and design and Nobel-prize winning scientists to create textiles inspired by science.

So... I think I may have found close coordinates for Tracy Island...

If someone has already done this, I apologise, but @madilayn‘s comments on this post got me thinking and I wanted to see if I could work it out as close as I could. The image is a little distorted because of John’s globe being rounded, and Maps just not, but pulling the image from Google Earth, and superimposing it onto the screepcap from the episode, it looks like TAG’s TI is located just south of Tonga, or in approximately that area, just, just off the Ring of Fire.

The numbers that I matched are as follows:


(-23.350326, -172.792969) (approx)

GPS Coordinates:

23° 21’ 1.1736’’ S 172° 47’ 34.6884’’ W (approx)

If anyone disagrees, I would be happy to be proved wrong!! :)


Science Spotlight: How Your Smartphone Knows Where You Are

Quantum physics, Einstein’s theory of relativity and atomic clocks that are accurate to one billionth of a second – all of these are crucial in allowing your smartphone to pinpoint your precise location almost anywhere on Earth. It’s called the Global Positioning System, or GPS.

The GPS receiver in your smartphone uses trilateration — a more complex version of triangulation — to determine its position on Earth. In drawings, trilateration is often illustrated in 2-D using circles. But since GPS deals with satellites and Earth in the real 3-D world, spheres are a better representation of what’s actually happening.
