Either I, and later John Cuthber, proposed using binary search algorithm. It can be used on alphabetically sorted list of available names of famous and/or personally known persons. It gives 33 questions for finding anybody living on the entire planet. But it can be used on any sorted list of data. https://en.wikipedia.org/wiki/Binary_search_algorithm If we limit only to English alphabet, a-z, there is 26 letters. You can find the first letter of surname in log2(26) = ~5 questions. Later the same with first name. Yet another one for gender. Yet another one for whether person is famous or friend. You could ask for age as well using binary search algorithm. If we limit age to range 0...128, exact age will be found in log2(128) = 7 questions (but I doubt such precision is needed). e.g. age of person is higher than 64? No. age of person is higher than 32? No. Age of person is higher than 16? Yes (this gives range 17...32) 19 questions to know: initials, age, sex and famous/friend status. It can be also done with month of birth log2(12)= ~4 questions, and day of birth log2(31)=~5 questions.

1) radioactive isotope of Carbon C-14 or Potassium K-40 decayed in the wrong molecule, in the wrong moment, destroyed DNA of some cell, caused mutation, which resulted in cancer.. 2) primary (or secondary) cosmic ray particle (the most likely from the Sun), hit DNA molecule, or surrounding it molecules, transformed them, and damaged DNA like above.. 3) free radical reacted with DNA, damaging it.. 4) [....] Some mothers, and fathers, "asked" for it by them self, by drinking alcohol, using cigarettes and narcotics, eating unhealthy and/or carcinogenic food.. Now we have "flood of stupidity", i.e. anti-vaccine movement.. If such people will win, and persuade politicians and spread their stupidity worldwide, we will see more children suffering illnesses almost destroyed in XX century in western countries, and you will go back to XIX century and earlier..

Programmers are splitting tasks to processes/services which are responsible for just one, or few things, instead of doing everything in one. It's also easier for developers: they're assigned to certain "project" and responsible for it and maintenance. However, services can be misused by hackers. Service made by hacker can be pretending the real service. On Windows OS, service can be automatically restarted when system detects it is not running (because has been shutdown by user, 3rd party process, or because it simply crashed due to internal error in source code). Admin can enable or disable this behavior in "Control Panel\System and Security\Administrative Tools\Services". Some services are so essential, that shutting them down, is causing restart of computer. In extreme situation this leads to infinite loop of restarts of machine. In such case, there is needed to start in safe mode, and find service which is restarting computer, and disallow it to restart, in admin panel. Go to this panel and you will see hundred services..

The worse than that can be only when some politicians have knowledge about crimes committed by judges (or unwanted unpleasant and reputation devastating stories from their life), and eventually blackmailing them, to support their case..

DNA degenerates over time of life multi-cellular life organism, rather than upgrades... DNA is damaged more, and more, and more.. Sometimes these random damages (mutations) are useful, but the most of the time, they're not.. If your hypothesis about "genetic memory" and "environment memory" inside of DNA is true, the most intelligent child should be born by the oldest parents. Some of them, might be smart, but not because parents memory has been stored in their DNA (and sperm and cell), and this way get to their children, but just because parents were smart and were talking with children, teaching them, and cared about good education (and had enough money for it, in countries in which university is not free of charge)..

@dimreepr No. You didn't propose any algorithm.. In binary search algorithm we split the all possible answers by two, so if we have initially e.g. 1 mln possible answers: /2 = 500k /2 = 250k /2 = 125k /2 = 62.5k /2 = 31250 /2 = 15625 /2 = ~7812 /2 = ~3906 /2 = ~ 1953 [.......] (repeat couple more times, and reach 1 possible answer) It's basically equation [math]f(x)=\frac{N}{2^x}[/math] - possible answers left.. 1) Am I living organism? Yes 2) Am I famous? Yes 3) Am I Woman? Yes 4) Do I have dog? Yes 5) Do I have pink car? Yes 6) Am I Paris Hilton? YES When there is 7.6 bln of people around the world, we can find anybody in the worst (but optimal) case in log2( 7.6*10^9 ) = 33 questions.. But that would require entire knowledge about the all 7.6 bln of people.. It's called "data partitioning" https://en.wikipedia.org/wiki/Binary_space_partitioning https://en.wikipedia.org/wiki/Partition_(database) ps. dimreepr OP question could be rephrased to: is it possible to ask such a question which will eliminate the more possibilities than division the all possible answers by 2.. e.g. "Am I woman?" Is dividing entire population by 2, but "Am I am celebrity/politician/scientist?" is not, as very small amount of people are celebrity/politician/scientist..

Reflectivity/reflectance of material changes with temperature. Bullet accelerated to high velocity is heated by air resistance, which renders room temperature reflectivity graphs of e.g. Chrome useless to answer your question.

The whole point of asking questions in party game "guess who am I?" is to limit possible answers. Your question didn't move you any way forward in it.. so you basically wasted question..

Laser with enough power, can melt flying bullet, and then vaporize it... In the case of rocket, there is needed just little damage which will cause malfunction of electronics and/or engines.

What is source of Tin.. ? Pure metal or some ore (contaminated by 3rd party compounds).. ? What is source of H2SO4.. ? Do you have raw Sulfur or ready sulfuric acid or some sulfate salt.. ? One (probably not very efficient) way would be electrolysis of metallic Tin, and then mix it with H2SO4. Then heat it to remove water. From Wikipedia page about SnSO4 "Sn (s) + CuSO4 (aq) → Cu (s) + SnSO4 (aq)" https://en.wikipedia.org/wiki/Tin(II)_sulfate

First, human should have regular station on the Moon...

...implants to brain which will take energy from organic compounds, with built-in WiFi/LTE (or their modern equivalent versions), allowing to transfer data to/from brain, to somebody else brain or device wirelessly, at speed of light.. To somebody without ihem, it'll look like telepathy, mind reading or magic..

In chemistry process of production of certain chemicals is named after people who the first one used their process. It's much easier to say what you have on mind using "Haber process" than having to say "process in which ammonia is produced from gaseous Nitrogen from air and Hydrogen from methane".. calling it "process of production of ammonia" is not enough to describe it, as there is many different ways to do it. There is existing such "hall of fame". Nobel prize laureates. https://en.wikipedia.org/wiki/List_of_Nobel_laureates

First, you should show it to your local school mathematics teacher. Then he/she should show it to somebody on nearby university for verification..

Faith is not needed in this case. It's experimental quantum physics. Annihilation of electrons and positrons is responsible for ~7.64% of entire energy emitted by the Sun.

To find whether there is conflict between different customers, you could fill unsigned int by bits. Each bit, one day of month. unsigned int has 32 bits, enough for entire month <= 31 days. mask |= 1<<day_numer; Then find conflict by doing bit-wise and operation between couple masks. There is no conflict, if returns 0. if( mask1 & mask2 ) { // conflict } Each room, 12 unsigned int masks for entire year.

Immortal "programmers" can wait, until they will die.. and then we will meet again..

...because scientists are disallowed to make experiments on living humans.. and their brains.. You can't even give experimental cancer drugs, to people at the last stage of their life, in the last days of their life, even if they would be begging for it..

...yet another reason to become immortal.. Oh, no! They never allowed me to have $1 debt...

The older you are, the more childish you are... Do you realize it.. ?

Greg, according to wikipedia page, is comedian (or attempting to be comedian ).. and he made joke about eating aliens.. You treated him as regular non-comedian person, but he is joker.. The end of story.

Is it the real work, or just exercise? I wouldn't tell customer which room number they are getting, just verify whether any room of type they want is empty at given date range, and give some code instead.. This would allow the most optimal room assignment.. If it's real work - why not show map with the all rooms, with the all dates, and let people pick up on timeline.. ? We have here cinemas in which you can log in, and reserve seats, and buy tickets on-line. There is showed entire cinema room which is playing movie (each room has different settings of seats, in rows and columns, and stairs between them), with the all seats as buttons. They are green or red, indicating whether seat is already reserved or not. User can click on them to reserve them. In hotel website you could even show virtual visualization of each room (spherical mapping), scrollable in H and P axes.

Everything? Also changing results of mathematical equations? e.g. 1+1 wouldn't be 2 anymore? e.g. 2^8 wouldn't be 256 anymore? e.g. [math]\pi[/math] wouldn't be ~3.14159265 anymore? etc. etc. ...for sure mathematics is excluded from omnipotence..

The largest slob of the Universe. Does not even have retirement funds... "If God had a name what would it be? And would you call it to his face? If you were faced with Him in all His glory What would you ask if you had just one question? And yeah, yeah, God is great Yeah, yeah, God is good And yeah, yeah, yeah-yeah-yeah What if God was one of us? Just a slob like one of us Just a stranger on the bus Tryin' to make his way home? If God had a face what would it look like? And would you want to see if, seeing meant That you would have to believe in things like heaven And in Jesus and the saints, and all the prophets? And yeah, yeah, God is great Yeah, yeah, God is good And yeah, yeah, yeah-yeah-yeah What if God was one of us? Just a slob like one of us Just a stranger on the bus Tryin' to make his way home? Just tryin'… "

Omnipotence is e.g. ability to create the new Universe..
