It costs billions, and takes years to bring up the sort of manufacturing plant and infrastructure needed to produce silicon. It is happening, but the investment and expertise needed to do it means it’s limited to a handful of countries that are realistically capable of doing it. There’s also a huge risk of he investment not paying off in doing this too, most of the worlds high tech manufacturing is based in the Far East too, plonking a silicon fab in somewhere like North America makes it more expensive due to labour rates and the cost of shipping chips to the point they’re assembled into pcbs

It's a combination of several factors others here pointed out.

Beer is a pretty decent diuretic (makes you pee).

It's practice/addiction/tolerance to be able to drink any amount of alcohol, but beer is weaker than spirits or wine, so you can filter it quicker.

Finally, beer is mostly water. If you're constantly drinking and peeing it out, you can go through it quite quickly (like water) while your system is filtering.

The general rule of thumb is 1 drink/hr filtration. Be that a pint, a glass of wine, or a shot of hard liquor, the filtration rate is roughly equal. Food alters this rate too. Pizza is paired well with beer because it's highly filling and stays digesting for a long time compared to something better for the body, like a salad. So on a full stomach of pizza, you can drink more than an empty stomach, but not suffer from the same intoxication level.

Beer also has a sugar content, but nothing like the orange juice you mentioned. It has some sodium, but not a ton, like soda, and is one reason why water is toxic if you have too much, causes sodium deficiency.

I say this as an avid drinker of all adult beverages other than tequila.

Light gets refracted every which way in a rainbow thru water droplets in the air - depending on the wavelength of light and the angle it passes thru a water droplet. But, in the center of the rainbow, refracted wavelengths or colors combine with refracted colors from other droplets to make white light again. That's why the center of a rainbow is often brighter than the surrounding sky. The bands of colors we think of as a rainbow are just the edge where colors are refracted at angles that don't combine with other colors.

Because its incredebly hard and incredebly expensive to do. Being extremly woried about suply chains for geopolitical reason is a thing that came back with Corona and even more so with the russian war against ukraine. Why invest billions into something with no or litle monetary benifit if in the last 30 years nothing has happend that interuped the existing supply chains. On another note its not just sensitive to geopolitcs in SEA and EA its just as depended on Western European and American geopolitics. So if you realy want to become indepened from the rest of the world for chips be ready to invest proably hundred of billions and if nothing happens in Taiwan you gain basicly nothing.

TLDR: Because companies don't play geo-politics, they only care about low manufacturing costs and profits. It's only now that the US and other Western governments are getting involved that chip manufacturing is finally getting spread to other countries. Because Governments are the ones that worry about geo-politics and supply chain problems caused by rampant outsourcing.

In 1976 the Taiwanese government convinced RCA to transfer semiconductor manufacturing to Taiwan. Since then the semi conductor business in Taiwan has only grown and now upwards of 50% of chip manufacturing on the planet happens on that one island.

Taiwan has the advantage that it has the expertise in-house (lots of people with experience and training to make chips) and can do so at a much lower cost of labor compared to the US and other Western countries.

Similarly 60-70% of the worlds hard drives are also manufactured in Taiwan in 3 factories that are side-by-side in a tsunami/typhoon zone.

The next largest chip foundry is Samsung's which is in South Korea.

Meanwhile Intel and Texas Instruments still manufacture chips on-shore in the US. But while Intel's chips are critical to the PC industry, smart phones, automotive and a lot of other industries are heavily reliant on South Korea and Taiwan for their components and assembly.

It's kindof of shocking to be honest that Western Governments didn't take notice of the weakness of manufacturing industries heavy reliance on potentially unstable countries until recently.

The US Government has also been forced to step-in and stop the sale of US based telecom and electronics companies to the likes of Broadcom because of their Chinese backing.

Decades of outsourcing has lead the US in particular to be heavily reliant on countries like China and Taiwan for things like electronics. Even the Japanese which were historically an electronic manufacturing powerhouse are now reliant on other countries for chips because manufacturing them onshore is too expensive.

Meanwhile Russia is reportedly scrambling to buy black market chips because they too are heavily reliant on the West for electronics, and due to sanctions can't buy enough parts to maintain their own infrastructure or build modern military hardware.

Due to geo-political issues between Taiwan and China, and problems caused by the pandemic, Samsung is now building a new chip foundry in Texas which should be operational in 2024.

Because countries don't run manufacturing, corporations do. And up until now, it's always been cheaper to buy from Taiwan than to pay the reasonable wages and obey the environmental regulations in the US/EU. And there's exactly one thing corporations care about, and it ain't workers, the environment, or the wellbeing of a country.

They don't. The TV show Mythbusters disproved this back in the day. Cattle, like most mammals other than primates, are red-green colorblind.

The movement of the cape is what makes the bull attack, not the color. Red is just the traditional color of the cape because it hides bloodstains; pink and yellow are also common.

Other than the size of distant planets being much smaller than stars or galaxies. The other very important difference is that compared to stars and galaxies planets do not give off its own light. They only reflect the light from nearby source.

The difference is like seeing a candle over a mile away compared to finding a ball in a dark room. It's much easier for us to see the candle than the ball.

The way we find planets currently is by measuring if and by how much a star dims when the planet passes in front of the star. The more the star dims, the bigger the planet.
