No Ripping Up This Rental Agreement. And The Punishments for Not Looking After The Property, Not Paying

Bacteriophage. This is one of a few pieces I’ve submitted to a gallery show I’m having with my friends/coworkers at Tr!ckster in Berkeley. Tried a somewhat different approach than my usual on this one, and I like it. 

Probably will have little prints available soon. 

23 science facts we didn't know at the start of 2016

1. Gravitational waves are real. More than 100 years after Einstein first predicted them, researchers finally detected the elusive ripples in space time this year. We’ve now seen three gravitational wave events in total.

2. Sloths almost die every time they poop, and it looks agonising.

3. It’s possible to live for more than a year without a heart in your body.

4. It’s also possible to live a normal life without 90 percent of your brain.

5. There are strange, metallic sounds coming from the Mariana trench, the deepest point on Earth’s surface. Scientists currently think the noise is a new kind of baleen whale call.

6. A revolutionary new type of nuclear fusion machine being trialled in Germany really works, and could be the key to clean, unlimited energy.

7. There’s an Earth-like planet just 4.2 light-years away in the Alpha Centauri star system - and scientists are already planning a mission to visit it.

8. Earth has a second mini-moon orbiting it, known as a ‘quasi-satellite’. It’s called 2016 HO3.

9. There might be a ninth planet in our Solar System (no, Pluto doesn’t count).

10. The first written record demonstrating the laws of friction has been hiding inside Leonardo da Vinci’s “irrelevant scribbles” for the past 500 years.

11. Zika virus can be spread sexually, and it really does cause microcephaly in babies.

12. Crows have big ears, and they’re kinda terrifying.

13. The largest known prime number is 274,207,281– 1, which is a ridiculous 22 million digits in length. It’s 5 million digits longer than the second largest prime.

14. The North Pole is slowly moving towards London, due to the planet’s shifting water content.

15. Earth lost enough sea ice this year to cover the entire land mass of India.

16. Artificial intelligence can beat humans at Go.

17. Tardigrades are so indestructible because they have an in-built toolkit to protect their DNA from damage. These tiny creatures can survive being frozen for decades, can bounce back from total desiccation, and can even handle the harsh radiation of space.

18. There are two liquid states of water.

19. Pear-shaped atomic nuclei exist, and they make time travel seem pretty damn impossible.

20. Dinosaurs had glorious tail feathers, and they were floppy.

21. One third of the planet can no longer see the Milky Way from where they live.

22. There’s a giant, 1.5-billion-cubic-metre (54-billion-cubic-foot) field of precious helium gas in Tanzania.

23. The ‘impossible’ EM Drive is the propulsion system that just won’t quit. NASA says it really does seem to produce thrust - but they still have no idea how. We’ll save that mystery for 2017.

Architecture's "Political Compass": A Taxonomy of Emerging Architecture in One Diagram

Observing the architectural landscape today it’s clear that the type of work which is currently ascendant, particularly among young practices, is...

Considering how much architecture can impact the way we interact with the world, it’s fascinating to look at some of the emerging schools of thought in the field

This small scrap of cloth tells a much larger story of suffrage history.

This week in 1917, the National Women’s Party started picketing outside the White House for the right to vote. For months they protested silently, until a crowd began taunting them, throwing eggs and tomatoes at them, and tearing up their banners.

So the women made more banners.

A scrap from one was seized by police but eventually made its way to Alice Paul, the founder of the NWP and leader of the pickets, and then into our National Museum of American History. 

Methodology:

Characters were counted by hand based on UESP quest writeups. Characters were only counted if they were questgivers or involved in multiple quests. Only characters from the main quest or faction questlines were counted. Any expansions or DLCs have not been included.

Due to the incomplete documentation for ESO quests, that game probably has more margin of error than others, though it should be balanced out due to how many NPCs were counted overall. I realize that this is an imperfect process, especially considering the very different ways that each game handles quests. I think the overall patterns hold, though, even if the percentages might be off a few points were someone to repeat the process.

You’ll also notice that Morrowind, Oblivion, and ESO have two main quest graphs. The latter is for including characters who are also encountered in the other parts of the game. For Morrowind this is questlines where you must speak to all the house leaders to become Hortator, in Oblivion it is the Aid for Bruma questline where you must speak to the counts/countesses to gain their support, and in ESO this is the Weight of Three Crowns quest where the faction leaders convene on Stirk. Daggerfall, meanwhile, randomizes most of its quest, and the overall graph counts the main quest and nobles quests.

Sample sizes are as follows: Daggerfall (23 total, 10 main quest), Morrowind (82 total, 16 main quest, 34 with hortator), Oblivion (36 total, 9 main quest, 15 with Bruma allies), Skyrim (59, 11 main quest), ESO (278 total, 6 main quest, 10 with Stirk).

Conclusions and interpretations under the cut.

Terrifyingly accurate

I hear you! I’ve had three partners so far for competitions - it sucks when you don’t have anyone and I’m not entirely looking forward to having to find someone new when I graduate and move. There’s still a lot you can do on your own, though, I use a hoola hoop and mirrors to practice when I have to work on my own.

The Sad Part about my love for ballroom dancing

Is I have no partner. No one to dance with, or take lessons with, so I am left alone, to dream. Here’s hoping for a little ballroom and a little romance when I move. 

The Secret to Small Drone Obstacle Avoidance Is to Just Crash Into Stuff

Small drones bumble through obstacles just like bees

Roboticists are putting a tremendous amount of time and effort into finding the right combination of sensors and algorithms that will keep their drones from smashing into things. It’s a very difficult problem: With a few exceptions, you’ve got small platforms that move fast and don’t have the payload capability for the kind of sensors or computers that you really need to do real-time avoidance of things like trees or powerlines. And without obstacle avoidance, how will we ever have drones that can deliver new athletic socks to our doorstep in 30 minutes or less?

At the University of Pennsylvania’s GRASP Lab, where they’ve been working very very hard at getting quadrotors to fly through windows without running into them, Yash Mulgaonkar, Luis Guerrero-Bonilla, Anurag Makineni, and Professor Vijay Kumar have come up with what seems to be a much simpler solution for navigation and obstacle avoidance with swarms of small aerial robots: Give them a roll cage, and just let them run into whatever is in their way. Seriously, it’ll be fine!

This kind of “it’ll be fine” philosophy is what you find in most small flying insects, like bees: They don’t worry all that much about bumbling into stuff, or each other, they just kind of shrug it off and keep on going. Or, if you’re a roboticist, you might say something like, “The penalty due to collisions is small at these scales and sensors and controllers are not precise enough to guarantee collision free trajectories,” so stop trying to solve the collision problem, and just focus on not completely trashing yourself when you hit something. (Swiss startup Flyability was among the first to demonstrate the benefits of collision robustness by equipping a regular-size drone with a gimballed protective cage and flying through forests and ice caves.)

I want to see an adventure story set in medieval Bologna

Or Assassin's Creed

The city of Bologna in the 12th-13th century - the closest we can get to a medieval skyscraper city; because nobles used to build high towers as a symbol of power and also for offensive/defensive purposes, at one point there were around 100 such towers.

Don’t try this at home!

I talked about the interesting structure of graphite (aka pencil lead) in our latest video:

But I didn’t have time to touch on one of the fascinating side effects of this structure - graphite’s conductivity. A single, two-dimensional sheet of graphite (known as graphene) is the most conductive material we know about. Diamond is among the least conductive materials we know about.

Impure graphite - like the stuff we find in pencils - is somewhere in between. It’s more conductive than sea water and less conductive than steel. As free electrons flow through it, it lights up like a filament and puts out a lot of heat.

Some risk-taking YouTubers (MausolfB Education and ElectroBoom) demonstrated this property so you don’t have to.
