This car race involved years of training, feats of engineering, high-profile sponsorships, competitors from around the world and a racetrack made of gold.

But the high-octane competition, described as a cross between physics and motor-sports, is invisible to the naked eye. In fact, the track itself is only a fraction of the width of a human hair, and the cars themselves are each comprised of a single molecule.

The Nanocar Race, which happened over the weekend at Le centre national de la recherché scientific in Toulouse, France, was billed as the “first-ever race of molecule-cars.”

It’s meant to generate excitement about molecular machines. Research on the tiny structures won last year’s Nobel Prize in Chemistry, and they have been lauded as the “first steps into a new world,” as The Two-Way reported.

It’s been my experience that you can nearly always enjoy things if you make up your mind firmly that you will.

Building microfluidic circuits is generally a multi-day process, requiring a clean room and specialized manufacturing equipment. A new study suggests a quicker alternative using fluid walls to define the circuit instead of solid ones. The authors refer to their technique as “Freestyle Fluidics”. As seen above, the shape of the circuit is printed in the operating fluid, then covered by a layer of immiscible, transparent fluid. This outer layer help prevent evaporation. Underneath, the circuit holds its shape due to interfacial forces pinning it in place. Those same forces can be used to passively drive flow in the circuit, as shown in the lower animation, where fluid is pumped from one droplet to the other by pressure differences due to curvature. Changing the width of connecting channels can also direct flow in the circuits. This technique offers better biocompatibility than conventional microfluidic circuits, and the authors hope that this, along with simplified manufacturing, will help the technique spread.

Lava flows like these Hawaii’an ones are endlessly mesmerizing. This type of flow is gravity-driven; rather than being pushed by explosive pressure, the lava flows under its own weight and that of the lava upstream. In fact, fluid dynamicists refer to this kind of flow as a gravity current, a term also applied to avalanches, turbidity currents, and cold drafts that sneak under your door in the wintertime. How quickly these viscous flows spread depends on factors like the density and viscosity of the lava and on the volume of lava being released at the vent. As the lava cools, its viscosity increases rapidly, and an outer crust can solidify while molten lava continues to flow beneath. Be sure to check out the full video below for even more gorgeous views of lava.  (Image/video credit: J. Tarsen, source; via J. Hertzberg)

The Six Types of Middle-Earth Names

1. Characters whose Names are Secretly Insults: 

Samwise: means “Half-wise” or “Half-wit.” He is Stupid Gamgee

Faramir: Boromir’s name means “steadfast jewel”, but Faramir’s name just means “sufficient jewel.”

Sufficient.

Denethor took one look at baby Faramir and thought “eh I guess he exists or whatever” which is very in character

 2. Characters who Have Way Too Many Names

Examples include Aragorn son of Arathorn son of Arador heir of Isildur Elendil’s son, descendant of Numenor,  Thorongill,  Eagle of the Star,  Dúnadan, Strider,  Wingfoot, Longshanks, Elessar, Edhelharn, Elfstone, Estel (”Hope,”) The Chieftain of the Dúnedain, King of the West, High King of Gondor and Arnor, and Envinyatar the Renewer of the House of Telcontar

Wait I’m sorry did I say “examples” plural Cuz that was all one guy 3. Characters whose parents must’ve been prophets

-Frodo means “wise by experience.” His story is about becoming wise by experience -A lady named Elwing turns into a bird (geddit)

4. Characters whose families were so lazy that they copy-pasted the same first half of a name onto multiple people

Théoden/Théodred  Aragorn/Arathorn/Arador  Éomer/ Éomund/Éowyn/Éorl Elladan/Elrohir/Elrond/Elros/Elwing/Elenwë/Elendil/Eldarion (the laziest family) 

5.Characters whose Names are Expertly Designed so that Newbies can’t Remember Who is Who and Feel Sad

All the people mentioned in number 4 Celeborn, Celegorm, Celebrimbor, Celebrian All the rhyming dwarf names in the Hobbit Sauron and Saruman Arwen and Éowyn

6. Name so nice, you say it twice

Legoas Greenleaf: Legolas’s first name means “Greenleaf” in elvish. Legolas is Greenleaf Greenleaf (thranduil really likes green leaves ok) King Théoden’s name means King in Rohirric. Tolkien decided to name his king “King.” All hail King King  this is what the fanbase means when we say tolkien was a creative genius with language

Never be afraid to fail.
