well...the pictures are still hard to look at

while my experience with concrete is zero - is there a diff between cement and concrete? - i did put a penny in the fresh cement of our porch and when we wrote our names in the cement when we had the driveway done last summer. as for steel, i have several wartime steel cents in my coin collection

i don't know what to think about it

Concrete is a type of cement. Cement is just the generic term for a mixed solid of that type.

This is what I think, in regards to what the person in the webpage says...

Refering to my picture, the straight lines of the building are the angles viewable by the public. The dashed lines are the braces, not seen by the public eye. My theory on how the towers collapsed is as follows. As seen in the picture, you can see the general location of where the planes hit, not exact, but relatively close. Now, when the planes themselves hit, they took out some of the braces, how many, I don't know, but some, so that in itself is enough to lower the structure's integrity in itself by more than half. So, braces are left, not many, but enough to keep the structure standing. Now whether the braces themselves melted, causing the floors to collapse or not, I dont know, but think of this... Whenever concrete is heated to high temps, the moisture in it starts to boil, wanting to escape and this builds pressure. Now, due to the load on the concrete from the above floors, the pressure can find an easier way of escaping, by exploding. Now, this concrete helped support the beams in place, and since some of the beams are now missing, it puts even more load on the beams, all of this, and maybe even the heated beams, caused the top to collapse...

Also, he mentions how uniform the building were after collapse, and tries to prove how this is possible. He also says that there is no way the concrete dust formed was possible. I'll answer this in one simple answer... When something collapses like the towers did, the weight of whatever is falling is going to be threefold as it hits. Now, the weight of the upper structure falling downward is increased 3 fold. There is no way that the floor could accept that kind of weight, thus buckling. Alll of this crashing down, like dominos. So, he thinks that the top should have at least, in some portion, stayed in tact. Everytime it takes out a floor, it creates momentum. So when if has no floors to land upon, thus, finally finding the ground, it hts, and hard. It is like a car, going extremely fast, hitting a brick wall.... Flattens out like a pancake... And the concrete dust? Concrete crashing against concrete, breaks into smaller pieces of concrete, which, smack against each other making smaller pieces of concrete... This happening, over, and over, makes tons of dust...

In my opinion, I can't understand how he believes this didn't happen....

from what i saw on a documentay on discovery is that the towers went down it was because of the way the floosr where made and held in place, sorta like playing that block game jinga where you remove a block from the tower, well the floor were sorta stuck to the corners. then since their was alot of weight, heat, fire it caused them to brake away and then do a domino effect on the way down. just why the top part of the buliding didn't crumble at the same time or as quick well that how i think it was

That guy is stupid, his main argument is that steel doesnt melt,

Guy's a moron, site's stupid bs

the pictures are hard to look at but the article is very intresting. Your main argument is calling him a moron. He had facts and websites which prove what he was saying is correct and true.

Here's my response:

First off it's great he's looking at the fireside but one thing every seems to forget are the damn planes! Yeah planes hit the buildings, really big planes moving really fast. The planes didn't just land on the roof and deliver the fire they crashed into the frickin building. How do you even make a page describing how the towers couldn't have fallen and leave out the freaking planes?

And they were aircaft certified buildings and that means something now? So if I get into a frontal impact wreck in my car I'm guaranteed to live then right? Certifications mean nothing. Granted I'm sure that the spec does help somewhat they did stay up pretty long considering they were hit by huge damn planes, and I'm sure under normal use the certification might actually mean something, like say a small comuter plane, or accidental collision where a pilot actually tries to avoid it not hit fly through it.

Anyways I say he's a moron as well.

Further never believe anyone who tries to lure you in with the first few lines like: "I tried to believe", or "I tried to be patriotic". Whatever dude I don't fall for lame 3rd grade writing tricks.

    • Hands on with the ProtoArc EM25: Affordable ergonomic mouse that focuses on the right things by Taras Buria ProtoArc is known for making all sorts of office products with a big focus on ergonomics and comfort. Its latest product, the EM25, promises a comfortable-to-use, affordable, and customizable mouse. We took one for a spin; here are our impressions. The ProtoArc EM25 is a $49.99 mouse, but right now, during Prime Day 2026, you can get it for just $37.99. Right off the bat, you can see that the EM25 is inspired by Logitech's MX Master lineup and the legendary MX Master 3/3S. Its shape and proportions are very similar, so for a person with large hands (right-handed person, mind you), the EM25 is very comfortable to use. The mouse fills the palm, and the thumb rests on a small extension, giving your wrist a small tilt to reduce strain. The mouse is made of black plastic without any coating, eliminating long-term wear concerns. However, I can see the main buttons and other areas you touch the most getting polished over time. Despite its size and bulk, the mouse is not too heavy. It weighs about 100 grams, which is significantly less than the MX Master 3S and its successor. It is no lightweight gaming mouse by any means, but it is not excessively heavy like the MX Master 4. The EM25 has a built-in storage for its USB dongle. It is a cleverly made magnetic flap that you open by simply pressing on it. Next to the flap, you will find the on/off switch, the 1,000 Hz sensor, and a DPI button (up to 8,000 DPI). I find the DPI button location a bit odd, and I would prefer it somewhere below the main scroll wheel. Still, given that I never change DPI on my mice, I will let it pass. What is more important is that, unlike MX Master 3/3S/4, the device switch button is located below the left-click button, which allows you to switch devices without lifting and flipping the mouse. For a multi-device setup, this is a perfect solution: the button does not require too much effort to use, it does not get in your way, but it is also easily reachable with your thumb. The main scroll wheel has two modes: ratcheted and free-flow. You can only change between them with a bright orange button (I like this little touch of color), which is sprung and requires some effort to press. The wheel is dead-silent in free-flow mode, but ratched is quite loud and stiff, perhaps even too much to my liking. I can hardly call it deal-breaking, but it will certainly take some time to get used to. The side scroll wheel, it is notched, silent, and pleasant to use. Next to it, you can find a piece of glossed plastic with connection indicators: Dongle, Bluetooth 1, Bluetooth 2, and the low battery indicator. By the way, the built-in battery is rechargeable via a USB Type-C cable, which is included. It is sleeved and has an orange velcro strap to keep it tidy. After using the EM25 for a few weeks, I can say that its main buttons are my absolute favorite. They have very pronounced clicks, which feel great with just the right amount of force required to register a press. I would say they feel like something in between regular mouse clicks and silent ones. You can hear and feel the springy switch, but it is not sharp or loud to the point of annoying you. As for back/forward and device switch buttons, they are very clicky and quite noisy. Unfortunately, there are no extra buttons that you can map to specific things like in the MX Master lineup. Besides great primary clicks, another thing I like about the EM25 is its 1,000 Hz sensor. In the world, where Logitech still uses 125 Hz sensors in $100+ mice, seeing a much faster sensor in a mouse that costs three times less is very refreshing. Also, all the settings and customization you make are stored on-device, and you do not need to install any software. Just open the web-based app and change all that you need. Speaking of customization, you can remap what buttons do, adjust the DPI, and the sensor speed. Sadly, gestures are not supported, but you can still map pretty much anything to each button, including shortcuts, media buttons, and more. I also recommend using software like XMouseControl, as it will let you remap the side scroll wheel. At the end of the day, the ProtoArc EM25 is a great mouse. Clearly inspired by the MX Master lineup, it takes the best of it and complements it with a much more wallet-friendly price tag, significantly better sensor, on-device memory, a built-in storage for the dongle, and more (it fixes everything that I complained about the MX Master 4 recently). And for only $37.99 during Prime Day, the EM25 is an easy recommendation. Buy ProtoArc EM25 mouse - $37.99 | 24% off with Prime As an Amazon Associate, we earn from qualifying purchases.
