Without discrediting Nikola Tesla, most of what he did was based on the concept of flux density, which was already discovered more than 100 years before he was born. Faraday and later Gauss laid the foundation of Tesla's inventions without forgetting Maxwell who summarized everything beautifully in four equationsSomebody like Nikola Tesla for instance invented Alternating Current, Tesla Coil, Wireless Power Transmission etc. (Though Tesla is quite recent, but the technology at his time was also quite limited; for instance electricity had just been invented during his time). Developments from his inventions of electromagnetism, AC are applied in making Tesla electric vehicles. Rumour has it that the FBI confiscated many of Tesla's drawings and files after his death and nobody knows where they are. Probably being used/hidden by the government, as many cooperatives would lose a lot of money if his inventions were made public (As I said, this is a rumour, not sure whether this is true).
True that, smart people have been around throughout the ages, the ancients people would have definitely catch up with our technology with ease. Our generation most likely have been dumbed down with technologies in a way that we can't come up with original thoughts anymore. May be this explains why we've never had any paradigm shift since Einstein theory of relativity.I would say that modern engineers are more advantaged and benefit from their infinite access to knowledge and advanced technologies, therefore they can make structures that one could only imagine in the past. In the modern world, if for instance I am an architect, I do not even need to design a building. I just search the internet for plan drawings and put my name on them and no one will know they are not mine (Just emphasizing how advanced technology and access to knowledge have made things much easier). I am sure ancient engineers and architects would have cracked these modern technologies with time. In fact, some of the modern technologies were developed by ancient scientists. Da Vinci's drawings on aerodynamics, bridges, load bearing walls, war artillery are the ones used to make modern war equipment, aero planes, suspension bridges etc. Da Vinci studied the human anatomy, his drawings are used in modern medicine, making of robots etc. His drawings were so accurate and detailed and at that time, the electron microscope had not even been invented yet his drawings/developments from his drawings are the ones mostly used today. Therefore, to a certain degree, modern technology is dependent on past inventions.
Don't forget that there was a lot of ancient knowledge that was lost, since humans didn't have better means to keep records. So, we really don't know much of what they knew. Modern scientist are puzzled by the way the pyramids were made because of lack of knowledge the ancients Egyptians had. The Romans knew what type of clay and composition to cement stones together to support huge structures like aqueducts without steel reinforcement.
You pointed out how cool inside the pyramids are, that is one example of the ancient "advanced" knowledge. It could be the type of clay that dissipates heat at higher rate (just like space shuttle ceramic fiber), or the angle of reflection of the building or the whole structure was designed in such a way that it loses so much heat at night such that, it stays cool through out the day. They probably knew Newtons law of cooling 1000s of year before us.
While it's true that modern Engineers have a lot of tools at their disposal, Math and physics have hardly changed in the last 100yrs. In math particularly, we haven't had much breakthrough since 18th century. Every advanced concepts we use today like contour integration or Fourier analysis (in signal processing), were discovered over 200 years ago. The rockets Elon Musk sent to space, that is just 17th century Newtonian physics.
People like this OP don't understand the amount of details and time it took to design the integrated circuits to make such a magnificent Las Vegas dome. Of cause, you have to be intelligent to understand that. There is a good reason why intel forced PC manufacturers to put "intel Inside" label on every PC because there was a bunch of people who didn't know what was powering those computers.
Science is developmental/gradual. It is true Faraday for instance is known for his theory of electromagnetic induction. But other people come and develop it. It is made to be better than what was invented. Eg, smartphones use electomagnetic induction for wireless charging. This is and advancement of Faraday's electromagnetic induction studies. This does not mean that Faraday invented wireless charging, or did he? There were no smartphones in the past, his invention was used to develop a technology that could charge smartphones without the need of wires. Therefore, it is gradual and not that since it was invented years ago then that's just it. The developments that build on those inventions are equally to be creditedWithout discrediting Nikola Tesla, most of what he did was based on the concept of flux density, which was already discovered more than 100 years before he was born.

Who post pictures of cities here except you Kenyans? You daily post Nairobi pictures repetitively. Allso your fellow has explicitly said those are rumours so what is there to discuss about those rumours?I like the fact that when you started discussing serious things, the buffoons that were arguing with you vamoosed. The most intelligent thing they can do is search photos of cities only and post them and shout how they are better.
Math and physics hasn't changed much, only few details here and their but most of what has changed in the last 100 years, is the application of math and physics in the area of electronics. The invention of transistors and later on, integrated circuits, have laid the foundation of our modern lives today, compared to the times of vacuum diodes.Even if there hasn't been any major groundbreaking in the field of Mathematics/Physics, you cannot really compare the situation in the 1700s to that of today. Things like the internet and computers were discovered almost at the end of the 20th century. So the two periods cannot be the compared equally, right now we are definitely more advanced. Scientists like of the 20th century like Einstein, Tesla etc had no advanced tools for doing complex Mathematics and probably relied on their brains for those complex calculations. While today, majority of the people, above the 95th percentile cannot even do a simple Mathematics problem. I just develop a headache from calculating 21-9 (21 minus 9) off head. But we have computers that can do it for us with ease so why should I strain my brain?
True that.As much as the modern engineering is complex, so is the old. Designing integrated circuits is as difficult as constructing a Gothic cathedral in 1100 AD. That is why the ancient marvels are preserved to avoid losing their ingenuity. Many modern scholars have spent years, some even their entire lifetime, studying the construction technologies used in ancient construction.
You're confusing between a scientific discovery and application of it. As far as physics is concerned, wireless charging is an 18th century technology. It's just an induced emf, discovered by Faraday and laid out mathematically by Maxwell.Science is developmental/gradual.

Utajiabisha ukiskiza hizo stori. Even starlink themselves had promised a launch date in Kenya which didn’t happen until much later
Ushaaambiwa ni majaribio ya awali na haya majaribio yatafanyika ndani ya miezi minne wewe unaumia nn sasa 😀😀😀😀😀😀Acceleration from 0-80km/h is always less than a minute in cars. For electric trains acceleration from 0-80km/h should be less than 30 seconds
Baadae pia tuwaone humu ndani😂😂😂Haiya !!!.. ile Nyoka ya Best 007 imegeuka kuwa konokono….🤣🤣🤣🤣🤣🤣
Haka kaeneo kanakuja vizuri sana. Kuna Park, Vituo vinne vya BRT vipo karibu karibu, Msikiti mkubwa na kanisa kubwa , Soko kubwa , Hospital na Ofisi za Serikali. Hapa panakua Ka eneo kakumaliza vitu vingi pila kufika mjini 😎Magomeni hii, sijawahi kuona picha ya BRT kwa pembe hii.
Change in what wakat slums ziko kila Kona na kila angle 😂😂😂😂😂😂More of such are coming up rapidly,, Nairobi will really change 5 years to come
I get what you are trying to say. The credit for discovering electromagnetic induction definitely goes to Faraday. But there are other instances where one could also make another discovery out of it and still get credited for it.You're confusing between a scientific discovery and application of it. As far as physics is concerned, wireless charging is an 18th century technology. It's just an induced emf, discovered by Faraday and laid out mathematically by Maxwell.
