Why Are LEDs so Popular now As Opposed to Before?

Price, variety, availability and regulations.I just checked on Lowes site and LED bulbs are now cheaper than incandescent bulbs. Couple that with the energy savings (usually only 10% of the power required for the same lumens) and longer life means that LEDs are cheaper to buy and cheaper to own.

Over the last few years I have seen the variety of LEDs grow from the standard A19 to pretty much every shape. I have even seen LEDs that have a "filament" look.I have seen LEDs available virtually everywhere including the 7/11 near me.

Governments around the world have passed regulations banning incandescent bulbs allowing for the phase out of these older bulbs in favour of more energy efficient bulbs.The first incandescent replacements were CFLs (Compact Fluorescent Lights) and those were a real pain in the arse taking an increased time to reach full brightness as they aged. Compared to CFLs, LEDs are instant on, last longer and use less energy (about half that of CFLs).

That is why LEDs are now so popular.

How were the Germans able to fight against almost all the world and almost won twice?

We didn't "almost win", much less twice.I you are the attacker and prepare well, you always get some initial successes. However, sooner or later it becomes a numbers game (square miles of occupied area, miles of supply lines, equipment and personnel count and replacability, ...) and that's when you lose.

Germany and Japan hoped to force an advantageous peace before the numbers caught up with them. However, the allies didn't panic and just played on until the inevitable conclusion.(Could we have won? Yes. By befriending and empowering the people in he east instead of treating them as sub-humans and trying to oppress and enslave them. But then we wouldn't have been Fascists, we wouldn't have wanted to conquer them and the war wouldn't have happened at all. So, given that we were the kind of people who started a war like WWII, we could not have won. As in "at all". Any "almost"-opinion is simply a consequence of not knowing about martial, economic and political realities.

Why was Darth Maul killed off in the first episode?

He had only one plot function: kill off the father figure of Qui Gon Jinn, and establish Obi-Wan as a powerful hero. The next episodes were about politics, moral corruption, and the fall of the Republic. Maul had no point after that-he was just muscle to show the return of the Sith and kill off a Jedi. Mind you, they could have done Tyrannus from the beginning, but I suspect Lucas did not consider the storyline until after the film was done. Like Rowling, Tolkien, Martin and many many other storytellers, he was making things up as he went. Probably this is also why Obi-wan Kenobi and Tarkin were killed in ANH-they werent needed. Tarkin was just associated with the Death Star and not an arc character, while Obi-wan had little to do except continue Lukes training, something Lucas compensated with by inventing Yoda.Whiny fanboys who are shallow and focus on just aesthetic were angry about it, and whined endlessly about it until a mediocre TV show brought him back simply because they like an angry bitter character and werent happy with the more sad and tragic Anakin character

If a person committed manslaughter (the person had no intention to kill anyone, in other words, it was an accident that killed another person and there were evidences that was an accident), does the person who killed deserve the jail, and why?

Quite a few years ago, a woman named Diane Whipple was returning to her apartment. Another woman named Marjorie Knoller had two dogs, presa canarios. Knoller opened the door to her apartment and the dogs ran into the hallway and viciously attacked Whipple. Knoller called the dogs back. They didnt immediately listen but eventually retreated into the apartment. But not before doing fatal damage to Whipple, including damage to her neck that caused bleeding from her carotid arteries. Knoller never called police and Diane Whipple died alone in the hallway.

Marjorie Knoller didnt order the attack and would have preferred, I am sure, that the dogs didnt attack Whipple.But they did. The dogs had been trained to attack. Marjorie Knoller knew it but she didnt care enough to keep her door closed and worse, once the dogs got out, Knoller didnt care enough to call paramedics to help the woman. Does this sound like, because the fact the death was accidental, that Marjorie Knoller didnt deserve to be in jail?.

When did the Dutch Empire start?

The Netherlands became independant after their rebellion wars against spanish rule during the thirty years war. The dutch later created huge navies from the new port of Amsterdam as they wanted to seize the rich resources in the americas that was colonized by Spain.The dutch navy confiscated spanish ships through piracy and founded colonies in places like New Amsterdam and Suriname for trade and new settlements. The Netherlands became rich and they founded banks that promoted overseas expedition. The dutch east indies company later accquired Malacca and Batavia through wars so they could monopolize the rich resources and dominate the overseas trade.The wars with England destroyed their navies and the french invasion during Napoleon weakened the dutch expeditions as their land was conquered. The british dominated the seas with their bigger and sophisticated ships which prevented the dutch to further colonise overseas nevertheless Indonesia was to be under the dutch rule under their allaince with the UK. The Netherlands gained new lands in europe but later Belgium declared independance and Luxemburg was to remain seperate. The rise of Germany and Nazi invasion permanently destroyed the dutch colonial empire in which they could not recovered.

Are aliens and UFOs real?

Proof of E.T.:The Foo Dogs are ancient. Under their paw, you will find a geometry that contains the vector equilibrium and, it is, according to Fuller: The vector equilibrium (viz., the cuboctahedron) is the zero starting point for happenings and nonhappenings: it is the empty theater and empty circus and empty Universe ready to accommodate any act and any audience.Modern Science suddenly raised its IQ-level for some reason and employed the high IQ of the second World President of Mensa, and accomplished a great TOE, THEN we have a problem. Because how did ancient man know about the actual structure of spacetime itself? There is no freaking way!I see three possibilities.1.Aliens visited us in the past, and secret societies guard their secrets. Suddenly, the Kaaba in Mecca became a lot more interesting.

2.

Atlantis was real and humans have been advanced once before. Survivors spread the knowledge, which secret societies now guard.3.Our ancestors, the shamans, were exposed to advanced intelligences through DMT.

All three can be true. But if nr 3 was true, I believe the knowledge would be exoteric.Whaddya think? See any other possibilities?

Why did Apple release the iPhone 8 at the same time as the iPhone X?

Think of it this way.Have you ever gone to a fast food chain where there are three drink options.The small size is for $2The medium size is for $4And the large one is for $4.5Did u notice that the change from a medium size to a large one is only .

5 dollars as compared to the change from small to medium which is $2?Everyone thinks that see because the difference is so tiny I might as well upgrade from medium to large because I am getting so much more for Such a small increase in price.Its the same way for the iPhones.People set out wanting a new iPhoneThey shortlist the 8 because its cheaperThey then realise that the iPhone 8 has very little newThey then think that for just a few hundred dollars more I am actually getting so much moreSo they wait for the iPhone X to come.Because initially if only iPhone X would have been there then people would have noticed the stark increase in prices from 7 to X.

But now theres an intermediate phone which will actually make people buy the X

How did the Fourth Crusade play a role in the Byzantine Empire's downfall?

Depending on your perspective, one could argue that the Fourth Crusade was the downfall of the Eastern Roman (Byzantine) Empire. What remained of the Byzantines after that, other than the conquered subjects within the Latin Empire, were some small kingdoms that at the fringes. Though they did carry on much of Roman/Byzantine culture in general, they did not really carry on the imperial traditions, which were lost in the conquering of Constantinople. And they did not have anything remotely approaching the influence the Empire had had, even after they recaptured Constantinople.So in essence, after the Fourth Crusade, what was left of the Byzantines tried to recreate their former Empire. That they were able to conquer the Latins finally was only because the Latin Empire itself was not much of state. After finally retaking Constantinople, the main reason the Byzantines were able to hold out against the Ottomans as long as they did was because of the fortifications built centuries before. When the Ottomans entered the city they were surprised at how pitiful the Byzantines were, a shadow of what the Empire had once been

If electricity flows positive to negative, then how can the resistor come before the LED

Imagine an electric circuit as a roller coaster. When you get on the ride you usually have a beginning climb where the coaster pulls the train along a chain up to a height and then the ride begins.The initial climb is similar to your battery. It brings up the potential voltage to a certain height and the rest of the circuit is physics at play.Just like hills on a roller coaster track, resistors and LEDs have a voltage drop associated with them. This means they are using up that potential energy, (voltage in your circuit, loop in your coaster)At the end of the ride, (assuming you stay on the ride) you will have to be pulled back up to the top by the chain again because you have no more potential.

All that being said there are many differences between roller coaster physics and electricity which are not relevant to your question.Should you choose to continue learning about circuits and electricity Id like to plant a seed with you that although we think of electrical current flowing from to -. It is actually the opposite.Happy Learning!

The New Technology of OLED 5g TV Will Be a Turning Year for the Color TV Market in 2020
As the only truly mass-produced product in the next generation display technology roadmap, OLED is ushering in a "highlight moment" - although the sales growth in 2019 is limited, the joining of Huawei and Xiaomi is shaping a new image of "OLED".The killer mace of Internet brands?Recently, South Korea reported that LG display will supply OLED panels to Huawei, and the two companies are negotiating the supply. It is reported that this will be an emerging "TV" with 5g function.Lenovo thinks that the 5g package of the three traditional telecom operators has been officially launched in China; The fourth 5g license has Zhao Jingchun, chairman of China Radio and television. At the recently held world 5g conference, it was revealed that China Radio and television will promote 5g business for individuals next year. Huawei's smart screen series products will receive a "completely different product form upgrade" in 2020, which is a high probability event.It is also reported that emerging TV manufacturers Vizio and Xiaomi plan to use OLED panels next year to enter the OLED TV market. It is even reported that Xiaomi has signed a supply agreement with LGD for OLED display panels next year.If the radio and television 5g network is commercial, a batch of 5g TVs must be listed before. This is a "great opportunity" for communication enterprises and Internet enterprises to enter the color TV market. Industry experts believe that not only mobile phone companies that have "news" at present, but also other mainstream mobile phone manufacturers may launch 5g TV next year.In this context, OLED products with continuous tight supply of display panels will be particularly popular: just as OLED used to be synonymous with high-end in the mobile phone market. 5g color TV market, this scene may accelerate. In particular, considering that the new capacity of OLED panel supply of LGD in 2020 is concentrated on the 8.5 generation line in Guangzhou, there is no reason for domestic brands not to "get the month first".Therefore, 5g OLED, as the killer mace of the color TV industry in 2020, especially the mobile communication and Internet brands, has a sufficient "value foundation".Reshape the value chain of color TV, new brand new technologyAt present, the pattern of the domestic color TV industry, in addition to Xiaomi's great success in market share and sales scale by relying on low price and high quality, the traditional disk is still not much different from that 10 years ago."Among more than 10 innovative color TV brands, only Xiaomi is still active in the front line!" this is a true portrayal of Internet color TV entrepreneurs in the past few years. In this regard, industry experts believe that this is mainly because the "new brand" has no "substantive technological breakthrough" except "image, price and more dependence on e-commerce"—— The old routine of price war has also brought financial pressure under huge losses.The biggest feature of 5g OLED combination is the "hardware technology" which is very different from the traditional mainstream LCD TV.Wu Zhanghao, vice president of LG display and Minister of TV business, predicts that the sales of OLED TVs in China will reach 300000 400000 units in 2019, and the sales of OLED TVs in China is expected to reach more than 1 million units in 2020 - this product with short supply and growth is a good helper for the new brand to "create unique" technology competition value.On the other hand, 5g TV technology is bound to create a new concept of "cognition" between traditional TV brands and mobile phone and other communication enterprises. As a global leader in 5g technology, Huawei obviously has outstanding advantages in all aspects, especially in the fields of 5g signal processing antenna, chip, codec and so on. Industry insiders believe that the technical core capabilities of 5g TV and Huawei smart screen will be improved across dimensions."The new round of communication brand TV is very different from the previous Internet concept brand: because this round of new brand entry has 5g, OLED, fan aiot ecology and more hard core content."The battle for high-quality resources begins. Should the color TV industry changeFacing the upcoming 5g OLED color TV war in 2020, what is the biggest variable? The answer is the battle for upstream resources.On the one hand, the supply of OLED TV panels is always insufficient, which greatly limits the improvement of OLED market sales. For example, the data show that in the third quarter of this year, Samsung Electronics sold 1.16 million QLD TVs worldwide, a year-on-year increase of 520000 and a month on month increase of about 70000. Similarly, as a high-end TV, LG OLED TV sold 1.06 million units in the first three quarters, an increase of only 1%.On the other hand, the supply of 5g related chips and other products is also in the "initial stage". Unlike 4G new products and system products, high, middle and low-end gears are fully supplied. In 2019, the layout of many mobile phone brands on 5g mobile phones actually received the restriction that the chip is not in place. For example, apple is a typical example.Therefore, in the expectation of tight supply, Huawei Xiaomi seizes the new technology of OLED 5g TV, which has the effect of "dimensionality reduction and attack on traditional brands". Industry experts believe that 2020 will be an extraordinary "turning year" for the color TV market!
