It a hex of an engineer (no offence)

Great news which hopefully will shape the buyer away from monopolies.

Is there an open source Android app with all these complications?

The features I need on a smartwatch:

- eink or lcd display, for always-on and long battery life.

- brightness adjustable LED, for night usage of the watch and as flashlight at night.

- physical buttons, for controls including music volume, skip to next or previous song.

- bluetooth calls and notifications.

- nfc payments.

- functionality allowing to COMPLETELY DISABLE all those fitness functions, such as step counting or heart rate measuring. FU Garmin, I hate you.

- app for plotting tides and moon phases.

- app for voice memos, then transfer to Android/iOS for converting voice-to-text and further editing.

- if the display is touch-enabled, make sure to make it LOCKABLE, otherwise it does self-activates in the shower if the message is received. FU Amazfit, I hate u2.

- solar panel on the sides or even maybe behind eink/lcd display.

At the moment I am using Tissot T-Touch Solar Connect: No nfc payments, no bluetooth calling, no flashlight at night, no tides/moons, no music control But, I never need to charge it!!!!! And I dont need to use my second hand to press the led button to check the time at night, because its a hybrid watch with luminescent arrows.

Why can't the decentralized social media be made? What are the technical obstacles for this? Why cant it run in your browser, users could store their content on their own devices and share it P2P. Noone knows whats being shared, no problems with censorships, regulations, laws...

I am genuine interested in details why and how US media didnt abide to China laws?

May I know why you consider it a joke? I obviously have no much clue about it all

Could you please explain how do you see the proposed dump?

Can reduce these to:

Thank you for spending time to share it!

No carbon based life in our universe has had enough time to build the Dyson swarm yet. Evolution needs time: https://www.nature.com/articles/s41586-023-06600-9#disqus_th...

I hear people often talk online saying energy in the future will be either free or very cheap.

Dont know what cheap means for them, but it will never be for free because abundance happens when the supply exceeds demand and I dont see the scenario where the demand for energy is declining in a long run.

Diffraction limit determines the fundamental beam divergence angle theta = lamda/pi/D, where D is the beam diameter, lamda is wavelegth of elwctromagnetic radiation (eg. light).

To minimize theta, we need to either increase D or decrease lamda.

Lets assume we would be able to make far infrared high power lasers, at say 10,000 nm = 1e-5 m wavelength.

Lets assume we would be able to make D, the diameter of our laser beam, similar to the diameter of a typical planet, for Earth it is ~13,000 km = 13e6 m.

Theta = 1e-5 / 3.14 / 13e6 ~= 1e-13 radians.

Sun is ~ 25,000 light years from the center of our galaxy, ~= 25e3 y 3e8 m/s 31.5e6 s/year ~= 1e20 m.

Laser beam diameter, there far away, would be: 1e-13 *1e20 = 1e7 m, similar to the diameter of Earth, not much further diverged, focused and delivering the wast amount of energy all over the planet thereby evaporating it to a gas.

Indeed, what you say about the melting far away planets is possible, in theory.

Lets assume the Dyson swarm would be built at 1 AU or 149,597,870,700 m ~= 150e9 m from the Sun.

Lets assume energy converting photovoltaics will be made of non-crystalline materials with a high light absorption coefficient allowing solar cell thickness of ~100 nm = 100e-9 m.

Sphere surface is 4pir^2, in our case 43.14150e9^2 = 3e23 m2 * 100e-9 m = 3e16 m3 is the total volume occupied by a Dyson swarm tech.

For comparison the volume of matter that Earth contains is 1e21 m3, which is 1e21/3e16 ~= 1e5 = 100,000 times larger than what is required for a Dyson swarm.

Elbakyan has several biological species named in her honor:

- Idiogramma elbakyanae, a species of parasitoid wasps discovered by Russian and Mexican entomologists in 2017.

- Brachyplatystoma elbakyani [es], an extinct species of catfish discovered by Argentine paleontologists in 2020.

- Amphisbaena elbakyanae, a species of worm lizard discovered in 2021.[58]

- Sibogasyrinx elbakyanae [c; d], a species of deep-sea snail discovered by researchers from Russia and France in 2021

Mass is energy, localised in space-time, thats why space mostly empty, but mot completly emty, not 0 Kelvin.

How to charge people for sending me an email? With hashcash or something?

I am a researcher working in the the field of charge transport, electric current, material conductivity etc. I am happy to help you understand concepts and answer any of your questions as much as I can. Please don't hesitate to contact me.
