2. Was invented specifically for this purpose? 3. Has it ever been used as such?

It looks like modern cars really are better when you adjust for survival bias My subjective impression is that modern cars are much more reliable than older cars. But I can see one reason why fans of classic cars might disagree with this impression and it is one of those factors that can seriously bias someone's' perception. It is simply that any old car ...

This belief seemed to spread in April 2011 via twitter. Due to Ryanair's reputation as being overly greedy at the cost of the consumer, I think many people have simply assumed that this claim was true. It does not appear that it has been looked into too conclusively, but the investigations that have been done indicate that the claim is not true. Popular ...

In an October 2015 test report by the Dutch 'ConsumentenBond' (consumer organization/watchdog) they report back on an earlier test started in 2013 (no link available) where 5 lights each of 24 types from 13 brands were tested. At that moment they had been running 20000 hours. They were switched 8 times per day: 2:45 hours on, 15 minutes off. 75% of those ...

UPDATE: Funny or Die have admitted that the video is a hoax on their site. Original answer: The "Huvr board" is most probably a hoax product. In addition to Jwenting's answer depicting the problem with the fact that a breakthrough technological achievement wasn't published in any form, professional, scientific or popular. Several sites on the internet ...

After doing some brief research, I found that it can be illegal in (at least) California - @DavePhD mentions in comments that similar laws also exist for North Dakota and Nebraska, and may exist for other states as well. 6980.54. (a) A locksmith licensed by the bureau shall be subject to the provisions of Section 466.6 of the Penal Code, and shall be ...

Yes, The Lego Group produces more Lego tires than tire companies produce "real" tires. The Wikipedia article for Lego Tires says: All tires (and wheels) for Lego products are manufactured by Lego, which has produced tires between 14.4 and 107 millimetres (0.57 and 4.2 inches) in diameter. In 2006 the Lego Group produced 15 billion individual pieces of ...

This "Bioguard X" bracelet is a hoax. The Ministry of Health Israel has issued a statement (translated from Hebrew) saying: The Ministry of Health would like to inform the public that after inspecting the information about the Bioguard X bracelet as claimed by the manufacturer, no evidence was found for any health benefit of the product. The bracelet ...

The excellent Skeptoid blog has an entry for this very question. It's an entertaining read and well sums up the typical reasoning behind the myth and debunks them. From his conclusion paragraph: However, there's at least one remaining possibility that can explain what's being reported, and it doesn't require any new discoveries about anatomy or fans, or ...

No... There is no evidence that copper bracelets are any more useful than a hologram, or an ion bracelet, or a piece of amber, etc. (See below for a minor caveat.) Any effect that could be out there is nothing more than the [placebo effect] (Link to abstract on placebo effect for this specific mechanism)1. If you had read the linked question, you should ...

The label is real. It is a joke on behalf of the manufacturer, the Norwegian company "Ugly Children's Clothing" (They now seem to be trading as Marius Kids; the history/relationship was too convoluted for Google Translate to adequately explain.) Evidence that it hasn't been faked in Photoshop comes from the various different sources of different clothes ...

Can anyone confirm if this actually takes place with RyanAir or with any other airlines? An indirect answer, but yes, Delta Airlines admitted to having made a similar system, in error, for a period of 19 days, in April 2012, where customers that weren't logged in were offered cheaper flights: In late April we began testing a new search functionality as ...

Yes, it is against the US Federal law. Yes, in theory it can cost you $1000 or 30 days' jail. Pesticides are regulated in the US by the United States Environment Protection Agency, in accordance with the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Clorox Clean Up Cleaner With Bleach contains ingredients that are considered pesticides. (I'm ...

The recipe The recipe is a secret. It is kept in a vault that is on display, but the recipe itself as with its other products are considered trade secrets. A trade secret is any information that allows you to make money because it is not generally known. A trade secret could be a formula, c­omputer program, process, method, device, technique, pricing ...

The question boils down to: Given we have an electronic device that can be triggered remotely (to lock or unlock a door), is it possible to produce a hardware-based solution that can trigger it by: touching bananas connected to hardware? pushing buttons on a wireless device in the shape of a wand? detecting when you raise your eyebrows, using a device that ...

The word "scam" suggests fraudulence - a deliberate intention to deceive. It is a strong accusation, and we should be careful about wielding it without evidence. Given Leap Motion claim that they will not charge until the product is shipped and that they bill via credit-card, which enables consumers and the banks to recover their money if they charge ...

The source MIT Technology Review article seems to answer your questions Earlier this year, OLPC workers dropped off closed boxes containing the tablets, taped shut, with no instruction. “I thought the kids would play with the boxes. Within four minutes, one kid not only opened the box, found the on-off switch … powered it up. Within five days, they were ...

Back in 2012 this probably wasn't answerable, now after Gazelle's research which was conducted in 2014 I can attempt to answer this. The good news: it prevents it from dying. The bad news: it isn't the most effective (more like least effective). Gazelle, an eCommerce company, which lets people sell their used cell phones and pays consumers for used or ...

According to this German web page, scientists from the Hochschule Albstadt-Sigmaringen have investigated this in 2006. It is reported that they compared three cleaning methods: rubbing with a microfiber cloth, using some fruit wash, and using just cold water. All three apparently had about the same efficacy, and could only remove about 2/3 of the pesticides ...

They probably do. While I couldn't find evidence for Louis Vuitton destroying their unsold products, except for the original article, there are proof for other companies doing it. H&M and Wal-Mart: The clothing retailer H & M promised on Wednesday that it would stop the practice of destroying new, unworn clothing that it could not sell at its ...

The main reason that you should not use table salt is because the .1% that isn't NaCl is usually some sort of drying agent to keep the salt from clumping and caking. Furthermore, table salts tend to clog up when wet. Additionally, the size and shape of the salt crystals will play into how the water softener works. Table salt is generally very fine, and ...

Is the depiction of the label accurate? Yes, the same information is available directly from the manufacturer, PepsiCo Canada: The "why" question is largely out of scope of the site. It seems likely to be simply a rounding or experimental error.

I think the answer is, Yes it certainly can. Is it likely? Electric toasters work much the same way as space heaters or hair dryers, in that they run a current through high electrical resistant wires to generate incredible amounts of heat. Most toasters tend to use Nichrome (alloy of 80% Nickel and 20% Chromium). Electrical resistivity at room ...

Directly from HPs website. A subset of their Inkjet cartridges are designed to stop printing after an arbitrary date as determined by them. For most of the cartridges which have this "feature" the user can override it. For other cartridges, namely HP 10, 11, 12, 13, and 14, they will fail without recourse after the predetermined date. Each cartridge ...

All the laser pointers I have seen, are in fact lasers. It's easy to tell, If you point one at a wall about 20 feet away, it will create a very small point of light, a few mm across. If you do that with a LED light, the beam, if it's powerful enough will be anywhere from half a meter to a meter in diameter. Only a laser can keep a beam that tight. ...

Yes, WiFi is significantly more efficient, as the protocol is completely different. Once association with access point is established, WiFi only uses energy for actual transmission of data. On the other hand 3G remains in high-power state even after transmission is done. source: "Energy Consumption in Mobile Phones: A Measurement Study and Implications for ...
