Ion gauges on one of our deposition systems.
Ionization gauges are commonly used to measure pressure in high vacuum. They look and operate very much like a light bulb. Electrons are emitted from a central heated filament (the glowing part) and accelerated toward a helical wire or “grid” around the filament. Some of these electrons collide with gas molecules and ionize them. The ions are then attracted to a collector filament, creating a current which can be measured. The magnitude of the ion current depends on the pressure and composition of the gas.

Cryopump on a sputter system.
Cryopumps are a common type of high vacuum pump. They operate by condensing or freezing gases in the vacuum chamber onto an array that is typically cooled down to 10-12 kelvin. Compressed helium gas enters a chamber below the condenser array, where a piston (the displacer) allows the gas to expand, removing heat from the system. The piston then pushes the helium out and back into a compressor, and the cycle repeats. The displacer and compressor in a cryopump make a distinctive rhythmic high pitched whistle that is a common sound in clean rooms and condensed matter physics labs.

The tip of a chameleon’s long, sticky tongue suctions onto its target just prior to retracting. This partial vacuum effect helps them capture prey as large as 10% of their body mass.

Люблю тебя, ты — мой мустанг.
Люблю, как по тебе играют блики.
Изящный корпус, длинный шланг.
Мой пылесос со вкусом ежевики.

Ask Ethan: Do Virtual Particles Really Exist?
“[you’ve written about] how virtual particles have real observable effects and how Quantum Fluctuations were experimentally proven a long time ago… and when [Neil de Grasse] Tyson explained nothing, he talks about how virtual particles appear and disappear, but other quantum mechanics shows like PBS space time has said they are calculatory tools, so which is it? There are so many conflicting statements that I don’t know which is right.”
So, you’ve heard of virtual particles: these particle-antiparticle pairs that pop in-and-out of existence, even in empty space. Do they really exist?
If you’ve ever wondered who to thank for your ice cold drink on a hot Summer’s day, it’s this legend: James Dewar. Dewar invented the flask that many of us use daily.
Dewar never patented his invention of the flask. Instead, it was later patented and renamed by 2 German glass blowers, who set up the Thermos company, giving the Dewar flask its common name - the Thermos! *Dewar shakes fist*
The Dewar flask works by placing a smaller flask within a larger one, and sealing them at the neck. Between the 2 vessels is a gap which has had almost all of the air sucked out to create a near-vacuum.
This vacuum reduces heat transfer between the drink inside your flask, and outside world, be it hot or cold. This is because there are too few particles in the vacuum for heat energy to transfer through it by conduction or convection currents.

1885 - Mark Twain publishes the “Adventures of Huckleberry Finn” in the US (pictured)
1901 - H Cecil Booth patented a dust removing suction cleaner
1930 - US astronomer Clyde Tombaugh discovers Pluto
2020 - Boy Scouts of America files for bankruptcy amid hundreds of sexual abuse lawsuits, suspending those claims

Vakuum kann sehr reizvoll sein… aber auch sehr schmerzhaft. Kommt drauf an, ob man es selbst macht, oder eine unbarmherzige Dame die Qualen steigert.
