MYSTERIOUS Ruins That Defy History!

 Origins Explained is the place to be to find all the answers to your questions, from mysterious events and unsolved mysteries to everything there is to know about the world and its amazing animals! 1. Pompeii, Italy There are many scary stories in history, but the story of Pompeii is one that we just can’t get over. This is the city that was built in the fertile valley near a volcano, Mt. Vesuvius. When it erupted, it caught people by surprise and buried the city in soot and ash and left it covered and perfectly preserved for hundreds of years. Now much of it has been uncovered and it is a sad historical marvel and many people were frozen in time forever. 2. Great Zimbabwe, Zimbabwe Sticking with Africa, let's head to Zimbabwe, which holds one of the biggest mysteries of the continent. It's called ... Great Zimbabwe. Yeah, does not really sound mysterious, does it? But don't let that fool you, there's more to this than you might think. 3. Thonis, Egypt If you're bi

HP Pavilion 15 Review

 The HP Pavilion 15 gaming laptop is available with AMD’s new Ryzen processors, but due to high demand that was out of stock. Rather than skip it, I thought it would be interesting to review the Intel model instead and see how well quad core gaming laptops hold up towards the end of 2020.

HP Pavilion 15 Review
The HP Pavilion 15 gaming laptop is  available with AMD’s new Ryzen CPUs,   but due to high demand that one was out of stock.  Rather than skip it entirely, I thought it would   still be interesting to take a look at the Intel  model and see how well quad core processor stacks   up in late 2020, as 6 cores are pretty common  now even in lower end models thanks to AMD. The laptop has a black and green color scheme.  The lid is matte black with shiny green HP logo,   while the interior is black too with accented  green keys. It seems to be primarily plastic,   but the build quality feels decent for the  most part with no sharp corners or edges. There was some flex to the keyboard, but not  enough to be noticeable during regular use.   The lid was a bit more flexible,  owing to the center hinge design. The Pavilion 15 weighs around 2.35kg  or 5.2lb with a hard drive installed,   or just under 3kg or 6.5lb with the 200w  power brick and cables for charging. Given the specs and use of Max-Q  graphics, I expected a thinner laptop.   It’s not big or anything, but I’ve had full  power graphics in a smaller space before.

My Pavilion 15 has a 15.6” 1080p 144Hz screen,   no FreeSync or G-Sync and you cannot disable  optimus. There’s no Max-Q dynamic boost either. I’ve measured the screens average  grey-to-grey response time at 7.9ms.   I’ve got a link in the description if  you need an explanation on these numbers. When comparing against other gaming  laptops, it’s pretty similar to many   other 144Hz panels that I’ve tested, but a  little below the 6.9ms needed for transitions   to occur within the refresh window. I  can’t say I noticed ghosting though. I’ve tested the screen with the  Spider 5, and got 99% of sRGB,   70% of NTSC, 75% of AdobeRGB and 75% of  DCI-P3, so decent results for a gaming panel. Brightness was decent too, easily above 300  nits at 100% with an 880:1 contrast ratio. Backlight bleed was also good,   no problems with my unit but this  will vary between panels and laptops. There’s a 720p camera above the screen in  the middle, no Windows Hello support though. This is what the camera and  microphone look and sound like,   and here’s what it sounds  like to type on the keyboard. The keyboard has green accenting even with  the lighting off. The green lighting has   two levels of key brightness, and  all keys and secondary functions   are illuminated. At times the top row  of function keys felt a little small,   here’s how typing sounds to give  you an idea of what to expect.

Typing was fine in terms of key presses,  however it felt a bit uncomfortable for   me as I think I’ve got larger hands.  The wrist rest area isn’t very long,   so it’s difficult for me to rest my palms while  typing, instead they end up resting on the edge. The speakers are below this grill at the back  above the keyboard. I thought they sounded   pretty average for a laptop,  tinny without really any bass,   and the latency on results weren’t looking great. The power button is separate to the keyboard just  above it on the left, and it lights up green. The precision touchpad clicks  down anywhere and worked ok,   though it felt a little narrow due to the  aforementioned smaller space below the keyboard. Fingerprints and dirt aren’t too obvious on  the matte black interior, and they’re easy   enough to clean with a microfiber cloth.   On the left we’ve got HDMI 2.0 output, USB   3.2 Gen1 Type-A port, Gigabit Ethernet, USB 3.2  Gen2 Type-C port, and full sized SD card slot. The right has a 3.5mm audio combo jack, two more  USB 3.2 Gen1 Type-A ports, and the power input. The Type-C port does not have Thunderbolt  and it cannot be used to charge the laptop.   It does however offer Display Port 1.4 output,   and both this and the HDMI port connect  directly to the NVidia graphics.

The back has a couple of air exhaust  vents towards the corners and subtle   Pavilion branding in the middle.  There’s nothing on the front,   not even an indent to help opening the lid, but  this didn’t cause me any problems when opening. The bottom panel is clean with just air  intake vents towards the back above the fans.   Getting inside involves taking out 7  Phillips head screws, the three down   the front were shorter than the rest, and I  found the panel a bit challenging to remove. Once inside we’ve got the battery down the front  along with the single M.2 storage slot to the   right of that, while the 2.5” drive bay is on  the left. 

The WiFi 5 card is just above that,   and there are two memory slots towards the middle. Unfortunately the Pavilion 15 comes with  one stick of memory, so it’s single channel.   I did all my testing in this video  with dual channel for best results.   It’s at least advertised as one stick on the  HP website, so it’s not misleading like some   other companies, but they could offer a nice  speed boost by instead using two 8gb sticks.


HP Pavilion 15 Review
Their website listing isn’t all perfect though, for some reason they just list GTX 1660 Ti  graphics without noting that it’s Max-Q, and this has already led to at  least one disappointed customer. The Pavilion 15 is powered by a 3-cel 52.5Wh  battery. I’ve tested it with keyboard lighting   off, background apps disabled and screen at  50% brightness. It lasted for about 5 hours   in the YouTube playback test, so not too bad  for the size of the battery compared to others.

Let’s check out thermals next. Undervolting is disabled and the software  doesn’t offer any performance modes,   so there’s not too much to test. Idle temperatures were cool in my  21 degree Celsuis ambient room.   Stress tests were done with the Aida64 CPU  stress test with stress CPU only checked and   the Heaven GPU benchmark run at the same time,  while gaming was tested playing Watch Dogs 2. There was thermal throttling on the  CPU without using the cooling pad,   no thermal issues for the GPU though. These are the clock speeds for the same tests.  We see an improvement with the cooling pad in   use as it helps ease the thermal throttling.  There’s a bigger difference with and without   the cooling pad seen in the stress test,  which implies this test is causing heavier   throttling than my choice of game. 3.9GHz  was the best I could get in these tests,   not able to reach the full 4.2GHz  all core turbo boost of the 10300H.

The power limits of the processor are dynamic  based on cooling. For instance in the stress test,  PL1 was set to around 31 watts, though it would  change, then with the cooling pad PL1 was set to  41 watts, so it’s not static meaning performance  should improve the more you can improve cooling,   so better results with a thermal  paste change could be possible. Here’s how CPU only performance looks in Cinebench  with the GPU now idle. This is the only time I’ve   had the 10300H for testing, and the multicore  score was actually a little below the 8th gen   i5 just ahead of it in my Lenovo Y530, granted the  single core with the 10th gen chip was 7% higher. When idling the keyboard was a little below the  30 degree Celsius point that I typically see.   With the stress tests running it’s in the  high 40s in the center of the keyboard, warm but not hot. Let’s  have a listen to fan noise. The fans sounded silent to me at idle. Even  with the stress tests running it was quieter   than many other gaming laptops that I’ve tested,  too bad there’s no way to manually boost the  fans higher should we want to give thermals  were a limitation to processor performance  under heavy CPU plus GPU workloads. This is  an option their higher tier Omen 15 offers,   so it seems the Pavilion misses out. Now let’s check out how well  the Pavilion 15 performs in  games and see how it compares with other laptops.

I’ve tested Battlefield 5 in  campaign mode at ultra-settings,  and the Pavilion is highlighted in red.  It’s doing well for 1660 Ti Max-Q graphics,  ahead of the other Max-Q laptops I’ve  tasted like the Dell G3 or ASUS GA502. It’s even beating the higher wattage  2060 Max-Q in the ASUS G15 just below it, but as we saw in my recent video, the Zephyrus  is subject to thermal throttling in games. These are the results from Far Cry 5 with  ultra-settings in the built in benchmark. The results are still good relative to  other options, something I wasn’t expecting  as this test typically depends more on  CPU power, but the quad core i5 seems to be handling it well enough. That said, the  Pavilion 15 is now behind the 2060 Max-Q  in the G15 and G14 now, so those 8 core  Ryzen chips are likely what’s changed that. Shadow of the Tomb Raider was also tested with  the games benchmark tool with the highest setting  preset. The position of the Pavilion 15 doesn’t  change here relative to the same other laptops,  and again it’s the best result I’ve had from a  1660 Ti Max-Q based gaming laptop. The throttling  G15 with higher tier GPU is now behind again,  and interestingly the Pavilion I beating the  full 80 watt 1660 Ti in the older ASUS FX505DU,  which I think goes to show the limits of the  older Ryzen 3000 series, as all the other 1660  Ti non max-q laptops are doing much better.

I’ve also tested the Pavilion 15  in 21 games at all setting levels, check the card in the top right or link in the  description if you want more gaming benchmarks. Just as a recap, the last time I compared  a quad core i5 to 6 core i7 in games there  was little difference when looking  at the average results over 15 games,  and it still seems to be the case that 4 cores  holds up well enough today for gaming laptops,  though this could of course change in future  depending on the requirements of future titles. Now for the benchmarking tools,  I’ve tested Heaven, Valley,  and Superposition from Unigine, as well  as Fire strike and Time spy from 3DMark,  just pause the video if you want  a detailed look at these results.
I’ve used Adobe Premiere to export  one of my laptop review videos at 4K.  Lower times are better here, and despite  the lower overall specs the Pavilion 15 is still able to do well here due to the Intel  processor as this test benefits from quick sync. I’ve also tested Premiere but with the Puget  systems benchmark, and this tests for more  things like live playback rather than just  export times. Higher scores are better now, and  the Pavilion isn’t doing as well this time, more  in line with what I’d expect from the hardware.

Adobe Photoshop is a bit different, this one  typically depends more on single core performance,  and the i5-10300H does still have a  4.5GHz single core turbo boost speed,  so this result isn’t too surprising. DaVinci Resolve is more GP heavy, so the  score is fairly in line with where the 1660   Ti Max-Q would sit out of this selection of  laptops. So despite the quad core processor,  it’s scoring close to higher core count options. I’ve also tested SPECviewperf which tests  out various professional 3D workloads. I’ve used Crystal disk mark to test storage.  The 256gb NVMe M.2 SSD was doing quite well. The 1TB hard drive was doing how we’d  expect from spinning rust, and the SD  card slot wasn’t too bad. The card clicks in  and sits most of the way into the machine. Finally let’s discuss price, you can check the  links in the description for updated prices,  as these will change over time. At the time  of recording, the exact same configuration  I’ve tested here is $1100 USD on the HP  website, but there are a few different  options available including AMD Ryzen, again  links in the description for different options.

Honestly it doesn’t seem like great value when  you can pick up an 8 core Ryzen 7 4800H in the  Lenovo Legion 5. That has GTX 1660 Ti  graphics too, but they’re not Max-Q,  and it’s also $100 less. The Legion  also has FreeSync, better battery life,  and lower temperatures. Now to be fair, the  Ryzen Pavilion does seem to be priced a little  more competitively, but that’s been out of stock  for some time due to the popularity of Ryzen. The Pavilion 15 does at least perform a bit better  than other 1660 Ti max-q laptops I’ve tested so  far, and at least in gaming it does still seem  that 4 cores gets the job done today, though with   even gaming laptops under $700 these days having 6  core processors, I wouldn’t be at all surprised if   future games start taking advantage of that.  It’s also worth considering that my testing   was after a dual channel upgrade, for the $1100  price single channel memory is a bit of a tough   pill to swallow compared to alternatives. I’d  want a nice sale before considering this one,   but let me know what you thought about it  down in the comments, and of course if you’re   new here then make sure you’re subscribed  for future laptop reviews like this one.

Baffling Secret Revealed? 1100 Year Old Prasat Thom Temple, Cambodia

 Hey guys, today I wanted to show you the secret behind this ancient temple called Prasat Thom in Cambodia, at first look you think everything is completely ruined but I am going to show you something exciting. Look at these blocks, anything strange about them? Anything unusual ? Out of all the blocks, only these blocks have some type of markings on them? Do you see what they are? Now, let us just follow these blocks with those weird marking or designs. While the other blocks seem to have a flat top, these blocks seem to have a nice curved surface on top. There are a series of these stone blocks, all made of sand stone, each block is about 2 or 3 feet long, and they all look like bread loafs neatly arranged in a line. This is a pretty long line and at the very end, you see something quite interesting. A block that is curved and look what we see, a 7 headed snake, a Naga raised up with its hoods ready to attack. See the scales on its back, now you know what those markings on the stone b

The One Intelligent Thing That Alexander Did

 In history textbooks, Alexander is usually referred to as Alexander the Great. But was he really, or was he something else? Sadhguru speaks about the only intelligent thing Alexander did in his life. Sadhguru: So one reason he was pushing towards India was he wanted to find a yogi and learn how to become immortal. And they told Alexander, that we found the man, but he’s not willing to come. For once he did one intelligent thing, that’s the reason why we really removed his third name. See, Alexander,  in our history textbooks, school textbooks, they said, Alexander The Great. They only got the first name, the middle name, they missed out the last name, his name was Alexander The Great Idiot,  but because it was too long somebody left out the last name.  Well, the moment you make such a man, a great man in this world then in many ways, you’ve des…destroyed the future of humanity. Because from the age of sixteen – I think he died around thirty-two or thirty-three – all he did was kill, k

How does an Electric Motor work?

Electric motors can remain very mysterious! How do they use electricity to start rotating? Let's break it down step by step to understand how it works. Topics covered in this video: circuits, current, magnets, electromagnets, armature, commutator, brushes, stator, and rotor. This video only covers DC motors.  If you look around your house, you will see many devices that have electric motors, such as kids toys, table fans, toothbrushes, hairdryers, and this electric cutting knife. But how does the electric motor work? You turn it on and somehow it starts rotating. Why is that? Let’s start with something called a circuit. You have a battery, some wires and a device that uses electricity, such as a light bulb. Electricity flows through the circuit. But as soon as there is a break in the wire, the electricity stops flowing and the light bulb goes off. The path must be complete for the circuit to work. This is best down through the use of a switch. Electricity is flowing down the wire.

Kailasa Temple in Ellora Caves

  This is the world famous Kailasa temple at Ellora and let's look objectively into who could have built this amazing structure. By the end of this video, I hope you will agree with me that our history is completely wrong, and that this temple was built by a very advanced civilization. What is so special about this temple? This temple was not constructed by adding stone blocks, but an entire mountain was carved to create this temple. This is the only example in the whole world where a mountain was cut out from the top, to create a structure. In all the other temples and caves, even in Ellora and the rest of the world, the rock was cut from the front and carved as they went along. The whole world has followed a rock cutting technique called "cut-in monolith" while Kailasa temple is the only one that has used the exact opposite technique called "cut-out monolith". To see why this rock cutting technique is so different, let's take a look at this pillar that is

Strange Ancient Pyramid in Cambodia

 Hey guys, today we are going to look at a very strange place called Baksei Chamkrong in the Angkor Wat Complex in Cambodia. This is a very strange site because this is the only stepped pyramid in this temple complex. As you can see this is desolated, this is not a popular site but this is a perfect stepped pyramid and is one of the oldest construction sites in Cambodia. In fact there are inscriptions that actually take this back much much earlier in time. Who built this and why?  Archeologists and historians claim that this was built by a king called Rajendravarman and he spoke Tamil and Sanskrit. But there are inscriptions where he takes the entire Khmer dynasty to mythical times, more than many thousand years ago. This is a very interesting pyramid, and to understand it fully, we need to look at the aerial view. When we look at the drone footage, it is obvious that it was built with a specific pattern in mind. A specific frequency pattern. Remember, frequencies create patterns that
