Hooke's microscope was a simple design with a single lens, while modern microscopes use more advanced technology such as multiple lenses, improved illumination systems, and digital imaging capabilities. Modern microscopes also offer higher magnification and resolution, allowing for clearer visualization of tiny structures compared to Hooke's original design.
What else can I help you with?
When was the electron microscope invented?
1928 i believe by the Germans... someone check me on that... it wasnt the electron microscope we know today but it was the same concept only it magnified by a small 17 times... it has be improved since then
How does hooke's law effect today's society?
Hooke's Law, which states that the force needed to extend or compress a spring is directly proportional to the distance it is stretched or compressed, has numerous applications in today's society. It is used in the design of various mechanical systems like suspension systems in cars, shock absorbers, and even in the construction of buildings to ensure structural integrity under varying loads. Additionally, it is fundamental in fields like material science for understanding the behavior of materials under different stress conditions.
Who invented the electron microscope?
German physist Ernst Bruche invented it with the help of his assistant, Ernst Ruska. Sadly, his assistant betrayed him, and went to work for someone else. Ernst Ruska got the Nobel Prize for his invention, but it should have belonged to Ernst Bruche.Some Electron Microscope History:It is widely accepted that the first PROTOTYPE of an electron microscope was built by Ernst Ruska and Max Knoll in 1931; it was not more powerful than an optical microscope, but it demonstrated the principle that is still used in today's sophisticated and powerful instruments, and earned its builders a share of a Nobel Prize. In 1933, Ruska built a a new prototype instrument that was more powerful than any optical microscope, but still just an experimental instrument.The first PRACTICAL electron microscope was not constructed until 1938, by Eli F Burton of the University of Toronto along with students Cecil Hall, James Hillier and Albert Prebus.There does not seem to be any literature linking Ernst Ruska to Ernst Bruche, nor any literature relating any claim by Bruche to developmental work on the electron microscope. Some bibliography is going to have to be provided in order for the sad tale of Ruska betraying Bruche to be credible.
Who Discovered the inverse square law?
There is more than one kind of Inverse Square Law. French physicist, Charles Augstine de Coulomb (1736-1806) established the Inverse Square Laws of Electricity and Magnetism in 1785. [Electromagnetic Fields and Waves by V.V. Sarwate] However, the more controversial Inverse Square Law of Gravity is slightly convoluted. In the end it was Isaac Newton, but before you blow a breaker, let me try to explain. Ismael Bouleau only assumed, without much evidence, that gravity behaves exactly like light. Robert Hooke tried to sort out what Bouleau did wrong, but in his paper to the Royal Society in London, he used Newton's 3rd law of motion, and did not have the mathematical formula to back it. Hooke was a rival scientist of Newton, who also harshly criticised Newton's work. The famous Hooke/Newton dispute has gone down in history as Hooke states Newton stole his work in his "Principia" (1686-7) for the Inverse Square Law - as it pertained to gravity in the planets orbiting around the sun. In 1679, Hooke wrote Newton that "The velocity of a planet varies as the reciprocal of its distance from the sun," which was completely wrong. Christopher Wren challenged each of them to produce the math to prove Newton's law of universal gravitation follows an inverse-square law (just as do the effects of electric, magnetic, light, sound, and radiation phenomena). Only Newton was successful and his world view still dominates physics today. Seventeen Equations that Changed the World (2012) by Ian Stewart Electromagnetic Fields and Waves (1993) by V. V. Sarwate
Is the sentence Today is hotter than Tuesday is correct?
Yes, the sentence "Today is hotter than Tuesday" is grammatically correct. It compares the temperature of today with that of Tuesday, indicating that today is warmer.
What is the most powerful type of microscope today?
electronic microscopes
What did Robert hooke discover with the compound microscope?
He found the animalcule, which is known today as the animal cell
How are microscope different from today?
Microscopes have evolved over time with improvements in technology, such as the use of digital imaging and advanced optics. Today's microscopes offer higher magnification, resolution, and clarity compared to older models. Additionally, modern microscopes often come with features like fluorescence imaging and live-cell imaging capabilities.
Why was Robert hooke's discovery so important?
His discovery led to this improvement in science. He studied a dead cork [cell] and saw that it had many similar compartments that looked like holding cells, therefore the name Cells came to be. Robert Hooke saw the compartments with a special microscope that he built and invented. This microscope, however, was no where near as strong as the microscopes that we have today in our modern day technological lives.This is pretty much all that I can think of off of the top of my head, so BYE!!!
Types of microscope and their uses?
Compound microscopes can be found in most biology and science classrooms. They are electrically operated and use light to enhance the image of a cell. They will have multiple lenses for viewing.Dissecting microscopes are also known as stereo microscopes. They have low magnification and are also light powered. These microscopes can view objects larger than what a compound microscope is able to handle, in three dimensions.Scanning Electron Microscopes use electrons instead of light to create an image. These microscopes produce three-dimensional images with high resolution and magnification. They also have a larger depth of focus.Transmission Electron Microscopes use electrons instead of light to create an image. The material prepared must be very thin. The beams of electrons that pass through it give the viewer high magnification and resolution. These give two-dimensional images.Electron microscopes are one of the most advanced microscopes used today. This microscope is powered by a beam of electrons with very short wavelengths. These electrons strike objects that come in its path and helps increase the resolution of the microscope. The electron microscope is one of the types of microscopes used to study cells like tiny viral cells as well as larger molecules.
What is the difference between trinocular and binocular microscope?
A monocular microscope has only one eyepiece while a binocular microscope has two eyepieces with different lenses. Binocular microscopes are more popular today than the monocular microscope for professional use. Binocular microscopes have a pair of eyepieces, each with two or more lenses. This allows the operator to use both eyes thus doing away with the eyestrain usually caused by a monocular microscope. Trinocular microscopes or dual-view microscopes on the other hand are microscopes that integrate a digital camera. This allows the operator to views the image on a screen removed from the microscope itself. Trinocular microscopes remove the constraints of the eyepiece and allow the operators to work more comfortably and collaboratively.

The binocular microscope is easily the most popular type of microscope today. Binocular microscopes have a pair of eyepieces, each with two or more lenses.

What discovery started the study of cells and when did the discovery take place?
During the 1660's an English naturalist called Robert Hooke designed a microscope. It was not unlike simple school microscopes that are used today and relied on sunlight to illuminate the image. In 1665, Hooke made an accidental observation while looking at a thin slice of cork under his microscope. He saw something that he described as 'looking like a honeycomb with a great many little boxes'. Hooke called these boxes cells. He used this term to describe units in plant tissue (thick cell walls would be observed). He only saw the cell walls because cork cells are dead and without protoplasm.
