different
I would say that the discovery of Dark matter would be the biggest discovery. But other people may have other opinions.
We wouldn't have had the gas mask or the traffic signal.
The settlement of the plains would have been different without inventions. With the help of the spring-tooth harrow, grain drill, barbed wire, and corn binder it made it easier to support farmers. Without these, preparing soil, planting seeds, and protecting the land would have been very hard and taken more time.
An invention is a new, useful process, machine, improvement, etc., that did not exist previously and that is recognized as the product of some unique intuition or genius, as distinguished from ordinary mechanical skill or craftsmanship, and a discovery would be to be the first of one's kind to find, learn, or observe something. :)
It's actually not used in space shuttle windows. Aluminum and polycarbonate have very different thermal expansion rates so the polycarbonate windows would crack as they cool off when the space shuttle goes accross the dark side of the earth.
Depends on the base liquid of the marker. You would have to use a solvent of it that will not mar the polycarbonate.
No atomic bomb/energy =book, a bored and hard time to pass.
Life without pi would be different. M&M's would be square, the world, door knobs, most fruit, car tires, water bottle lids, marker caps and a lot more. Life without pi would be different to everyone, and would sure be hard to get used to.
Robert Boyle's discovery of Boyle's Law, which describes the relationship between pressure and volume of a gas at constant temperature, was significant in the development of the field of thermodynamics and laid the foundation for understanding gas behavior. Without this discovery, our understanding of gas laws and their practical applications, such as in the design of engines and air conditioning systems, would be severely limited.
You cant see a cell without just looking at it
You can buy a polycarbonate sheet from most DIY and building supply stores, such as Home Depot. They will happily cut the sheet to size for you if you ask them.
Yes, math would be different without René Descartes' discovery of analytic geometry. Descartes developed the Cartesian coordinate system, which introduced the use of algebraic equations to describe geometric shapes. This synthesis of algebra and geometry revolutionized mathematics, allowing for the development of new mathematical techniques and theories.
Sir Alexander Fleming is responsible for the discovery of penicillin. It was followed by the discovery of other forms of anti-biotics. Without his discovery the development of anti-biotics would have been delayed for some time until someone else made the discovery.
No, as it does not contain dioxins
Impossible* Hooke's discovery dealt with cells, which are extremely tiny that it is impossible to be seen with the naked eye. So, without the microscope, he would not have been able to see it.
food and water and different things that would help them to survive
