The term "wormhole" is about 50 years old. The conjecture, i.e. the Einstein-Rosen bridge, is 84 years old and is based on a special solution to the Einstein equations. Quite a lot of math is involved in this (e.g. Wick rotations), E-R bridge and Jaffries' development of same. The big potential payoff is a unified theory of everything - the grand quest of modern physics. This seems much more important than the Uberification of interstellar travel via wormholes popularized in space operas.
The universe will stop, and reverse time causing the everything to collapse into a singularity again. That means as the universe goes backwards, the dead will rise from the grave, humanity will eat excrement, un-chew food, and effectively vomit whole pieces of good. Oh, and you will reverse ageing until your a baby and get sucked up by a vagina.
Fun times.
This is the plot to "Yug Ylimaf" - the fourth episode of season 11 of Family Guy. This in turn may have been inspired by "Backwards' - the first episode of Red Dwarf.
LASIK is down to about $200 per eye, if you can afford a pair of glasses, you could probably afford to never buy them again.
The last time I got new astigmatic contacts, I discovered their focal length was further out than my arms could hold something I was trying to read. The brilliant solution of my optometrist was to try to sell me reading glasses...
Laser eye surgery will not fully correct vision if the patient has presbyopia. This means that you will still need glasses after the surgery. Many people over 40 develop this condition.
This reminds me of Van Eyk Phreaking (1982)- capturing electromagnetic emissions from computer monitors, keyboards, printers, etc. and reconstructing the digital data. This and the hard disk song are examples of side channel attacks. They exploit vulnerabilities in the implementation of a computer system rather than in its algorithms.

I once pointed out to a manager that a 1,000-feet serial cable coiled up underneath the desk was unnecessary when a 20-feet cable could have connected the PC to the modem. He said it still work and that was that.
That is 20 times the maximum cable length of an RS232 cable! "Cable length is one of the most discussed items in RS232 world. The standard has a clear answer, the maximum cable length is 50 feet, or the cable length equal to a capacitance of 2500 pF." https://www.lammertbies.nl/com...
Stuxnet was a worm, not a virus. "Computer worms are similar to viruses in that they replicate functional copies of themselves and can cause the same type of damage. In contrast to viruses, which require the spreading of an infected host file, worms are standalone software and do not require a host program or human help to propagate." cisco.com.
Not as easy as your think. The startup cost would be enormous. Very few engineers know, in detail, about thin film technology, it's kinda a lost art. just ask Kodak . The equipment would have to be custom made, no one has manufactured them in decades and the old one have long since been hauled off to the scrap yard.
ATR Magnetics actually did this. They had their own coating machinery made. That's studio recording tape, though, so the tolerances will probably be a lot lower than for ultra-high density digital media on extremely thin backing.
ATR seems to manufacture audio recording tape, not archival data storage tape. Magnetic storage drives run much faster than audio recording ones and they cannot be spliced if they break. Thus the specs and manufacturing costs are much higher. To be profitable a new company would have to sign up major cloud storage companies. These companies prioritize reliability based on "track record." A catch-22 situation for a startup with no history.
The wide spread belief in astrology is probably based on the Forer Effect. In 1948 Bertram F. Forer, a psychology professor, gave his students a personality profile test. The next day he handed out personality descriptions to his students and asked them if they were apt. The average score for the profiles 'accuracy' was 4.26 out of a possible 5 (perfect personality description). However, every student had been given the same analysis which consisted of statements from various horoscopes columns in the media.
"You have a great need for other people to like and admire you. You have a tendency to be critical of yourself. You have a great deal of unused capacity which you have not turned to your advantage. While you have some personality weaknesses, you are generally able to compensate for them. Disciplined and self-controlled outside, you tend to be worrisome and insecure inside. At times you have serious doubts as to whether you have made the right decision or done the right thing. You prefer a certain amount of change and variety and become dissatisfied when hemmed in by restrictions and limitations. You pride yourself as an independent thinker and do not accept others' statements without satisfactory proof. You have found it unwise to be too frank in revealing yourself to others. At times you are extroverted, affable, sociable, while at other times you are introverted, wary, reserved. Some of your aspirations tend to be pretty unrealistic. Security is one of your major goals in life."
This experiment has been repeated many times with similar results. People like general & mostly positive statements about them made by "authority" figures and that "affirm" their uniqueness.
The influence of a Google beta announcement can be enormous. When Google announced its 1 GIG gmail storage limit in April 2004 most of the free email providers quickly followed suit and have been playing catchup ever since. Wave may be the "killer app" for Google's Chrome OS. I believe that Apple owes its popular success (most users do not understand or care about the technical issues) simply to making a computer and interface that don't look like a computer. Google now has an application that does not look like an application. Instead users will be free to make it as spartan, ornate, simple, complex, large, small etc. as their fickle hearts desire. It's the sizzle that sells the steak not the nutritional analysis.
TANSTAAFL -there ain't no such thing as a free lunch - is the basis of thermodynamics.
A Brownian Ratchet is a thought experiment and has not been observed in the real world. I could do a thought experiment about suspending the law of gravity but the law of gravity would still apply in the real world. The article gives no specifics but strongly implies that someone has found a "loophole" in the Second Law of Thermodynamics.

Not to mention it sounds like a total ripoff... 94 dollars per update per radio? Thats highway robbery...
Highway robbery is the bane of traffic cops.
