The Concorde was a supersonic passenger jet, with an average flight time around 3 hours and 30 minutes between London to New York. As can be seen here Complete List of Concorde Scheduled Flight between 1991-2000 British Airways operated the following flights: BAW001 LHR-JFK /Daily/ DEP:10:30 ARR:09:25 BAW002 JFK-LHR /Daily/ DEP:12:15 ARR:21:00 BAW003 LHR-JFK /Daily/ DEP:19:30 ARR:18:25 BAW004 JFK-LHR /Daily/ DEP:13:30 ARR:22:25 The Atlantic states: With twice-daily service from London to New York, it was not uncommon for businesspeople to…

Recently a friend broke her arm while mountain biking and the bandages I was carrying proved invaluable for stopping(slowing) the bleeding and getting her away from the mountain. In the hospital they prescribed her TWO concurrent types of antibiotics to combat the jagged cut with inserted sand and offered her a tetanus jab. I know washing the wound with H2O2 is optimal while alcohol and iodine are not. But all those three are liquids and thus weigh rather…

As we already know that acceleration is a vector quantity which means that it has both direction as well as magnitude. It can also change given any one of the two or both (magnitude and direction) changes. Yet in the high school physics textbook of mine, it explicitly states that “the direction of the velocity of a body can change when its acceleration is constant” as a true statement which seems to contradict the premise…

As we know, some old lenses used Thoriated glass which give off non-negligible amounts of radiation. Although the radiation isn’t really harmful to the photographer, I’m wondering if it could be detected on film photographs. The radiation that hits the photographer would have had to travel through the film to get to him/her. (Nothing is, however, coming out of the eyepiece since the radioactive radiation doesn’t usually reflect off the mirrors like light.) For this SE, I’m…

This is a question I’ve had in my mind and have been a bit curious about. Let’s say I finish writing a novel but before publishing it, I want to get feedback on it. Should I publish it online somewhere? I was thinking having it online for free would probably discourage publishers from publishing your book. Is it fine to publish it online? If yes, are there specific sites that I should/should not use for…

I recently graduated (a couple of years ago) with a master’s degree in applied mathematics. During graduate school I began working on a paper, which I continued to work on in my free time post-graduation. A complete working copy of the paper is done and I have posted it on the arXiv here. The work contained in the paper is completely original and solves an “open problem” (the problem is open but not anything necessarily revolutionary).…

CNN’s Māori Party campaigns to change New Zealand’s name to Aotearoa links to Maoriparty.org’s petition Change our official name to Aotearoa. The Crown is mentioned in two paragraphs of the petition’s statement: Name changes over our whenua and the imposition of a colonial agenda in the education system in the early 1900s meant that Te Reo Māori fluency among our tupuna went from 90% in 1910 to 26% in 1950. In only 40 years, the Crown managed to successfully strip…

I was on a flight recently and the plane started to descend normally etc. However one cabin crew member randomly announced “remember if we have an emergency landing please leave all your belongings behind”. I know this is said on auto announcement but I have never herd it said on a descent. Anyway, suddenly the plane was going down nose down, controlled but lots of stuff rolled to the front. Several people were looking scared…

Trials of major terrorists happen quite often in Europe, but in America, it has taken 2 decades since 9/11 for the trial of the confessed mastermind to even start in military court. (This is longer than it took from the end of the Holocaust to capture and try Eichmann). Why is it so hard to put someone who has admitted his guilt and where there’s lots of evidence on trial? A complete analysis would be…

I’ve often heard that Infrared rays are called “heat rays”. However, I feel like this term is a misnomer. Don’t all the wavelengths of electromagnetic radiation carry energy?

Judging by how gamma rays are highly penetrating and are dangerous when absorbed by tissues, radiations of lower wavelengths should carry more energy, and should be able to increase the internal energy of the object that absorbed it much more than infrared rays can. This seems consistent with the conservation of energy for an isolated system:

I’ve started reading the “official” NES Documentation and in page ten, it says that “memory locations $0000-$07FF are mirrored three times at $0800-$1FFF”. My question is, what is the purpose of this mirroring? Wouldn’t it make more sense to use that space for other purposes or just to increase the number of available resources in a very limited hardware?

I was writing answers for my assignment about corruption, I put an example I took from an article from the web and cited it in APA format. I found out that my reference has been tagged as plagiarism. The title of the article which I wrote in my references was flagged as plagiarism because they found the title in the news site I used in my reference and other sites which uses it as a reference. I have tried excluding bibliography, with no success.

CAPX recently published a pro-Brexit opinion piece by John Longworth who headed a pro-Brexit pressure group. He argued that the UK were being held to ransom and were being treated like a “vassal state” of the EU in trade negotiations. He included a specific, unreferenced statistic that makes a strong and checkable claim: Another interesting statistic is that only 13% of the UK economy and 8% of businesses are involved with EU trade, the remainder being either purely…

The conventional model of the circulatory system assumes the heart pumps blood out of the ventricles through a series of progressively branching arteries of decreasing diameter transitioning to innumerable microscopic capillaries which then progressively converge as veins of increasing diameter connected to the atriums then back to the ventricles. Although the return trip through veins is assisted by skeletal muscle contractions squeezing blood through one-way valves, arteries lack valves and are assumed to be passive…
