The Mystery of the Binary Droplet

What goes on inside an evaporating droplet made up of more than one fluid? This is a perennially fascinating question with lots of permutations. (Video and image credit: P. Dekker et al.; research pre-print: C. Diddens et al.) Read the full article

is hydraulic oil flammable?

In a hydraulic system, fluids play an important role. The truth is no operation is possible for a hydraulic system without the presence of hydraulic fluid. The environmental changes such as temperature variations will affect the hydraulic fluids and working of the system. When the temperature increases, the fluid will evaporate and when the temperature decrease, the fluid will freeze. This is one of the major issues regarding hydraulic fluid. click here to know more...!

New discovery mmm

[mrvelocipede]

Found out at 8:00 this morning that some guys were going to come and pour the cement for the entryway floor. It further developed that they needed warm water, which meant attaching a hose to the washing machine supply, and then running the hose out the laundry room window and up the hill to the mixer.

Meanwhile, what we'd planned for today was a nice quiet morning of sleeping late, a bunch of cleaning, and then setting up the Christmas tree.

It has all been very exciting. By which I mean I wish our builder would give us a little more advance notice of these things.

Swimming Like a Ray

Manta rays are amazing and efficient swimmers -- a necessity for any large animal that survives on tiny plankton. Researchers have built a new soft robot inspired by swimming mantas.  (Image credit: J. Lanoy; video and research credit: H. Qing et al.; via Ars Technica) Read the full article

The concept of fluid? Smash

[hello-sweetheart]

It’s so cute to see small kids figure out the world.

I was in the mall and this little girl was waddling around with a sippy cup and she starts shaking it and sees drops of juice fly. So she opened the lid and just, shook it.

Then looked baffled at the mess, looked in her cup, saw there was no juice left, and started crying.

The mom had her back turned for one ☝️ second 😭

I just witness her discover fluid dynamics 🥹

Within a Drop

In this macro video, various chemical reactions swirl inside a single dangling droplet. Despite its tiny size, quite a lot can go on in a drop like this. (Video and image credit: B. Pleyer; via Nikon Small World in Motion) Read the full article

Liquid metal microdroplets enable soft, flexible electric connections across and through circuit layers

If a phone or other electronic device were made of soft materials, how would that change its use? Would it be more durable? If hospital health monitoring equipment were made of less rigid components, would it make it easier for patients to wear? While electronics of that type may still be far in the future, Virginia Tech researchers have developed an innovative method for constructing the soft electronic components that make them up. The focus of a project by the team of Michael Bartlett, principal investigator and associate professor in the Department of Mechanical Engineering, is on the circuits that manage all the electronic connections inside. Published inNature Electronics, this novel technique uses liquid metal microdroplets to create a stair-like structure that forms small conductive passages called vias. These vias create electric connections through and across circuit layers without needing drilled holes in hardware, as previous techniques have.

How do flat earthers think water works?

Like, let's believe them/follow their hypothesis for a second.

The Earth is flat. On land, we typically can't see for more than a mile or two because of how dynamic the surface of the land is with plattes, torsion, glacial deposits, erosion, etc. (Geologists, forgive me)

On water, the furthest you can see around you is 2.9 miles, despite the fact that water follows gravity in every other dynamic, being a fluid.

And you can see the moon, planets with reflectivity, and the stars and the sun for being more than that in miles away.

So, it's not your eyes or light that prevents you from seeing that far on the ocean.

So the earth is flat, your eyes absorb light from millions and billions of miles away, and you can't see more than 2.9 miles away from you on the ocean, in calm sunny seas.

You cannot see any land mass from even beyond the halfway mark across the Atlantic Ocean, the furthest you can see them is from 2.9 miles away, in calm, sunny seas.

How do the flat earthers think that works?

Do they think that water has hills beyond waves? How would glasses even get filled in such a world? How would your aquariums work?

you used to be able to have the flow depend on the downstream conditions

can't do that these days of course, because of choke
