Hertz – The Frequency Man

Моушн дизайн студия анимации в Киеве

Or Hz as he is more commonly known for his great leap in science and our knowledge of the invisible part of the spectrum, the light spectrum, the wave spectrum or the radio wave spectrum, the invisible waves that are US and OUR environment, increasingly.





While the introduction of wireless radio was a huge leap from copper connected phone and telegram, with far-reaching effects for humanity and technology ( including the Spanish flu?), successive leaps launch us into a soup of so many frequencies only dreamed of.





Heinrich Hertz, like Nikolai Tesla Maxwell and Edison were feeling the vibe and tapping into the opportunities of discovery from the electric field, from the aether.





Of interest and note, Hertz theorized and proved the Photo-electric cell which Albert Einstein subsequently won a Noble Prize for his re-iteration of it in a version that deleted the aether and took science and technology on a quantum physics journey of photons and atoms.

Therefore the Frequency man was very well in tune with the aether but not as attuned to Einstein and the path technology and wave propagation via apparatus and receiving devices, leading us here to 2020 and the clash of these titanic theorems, the consequences of and the opportunity to learn now what it all means, what the Frequency Man said and where its all led as we now spiral to dizzying heights of accelerating frequency, all of them impacting our bodies and environment for benefit or harm depending on the frequency and our sensitivity to it.





This is a brief introduction to Hertz and his wonderful discovery and his contribution to wave science. We will add more Hertz links from readers information and links as well.





The man behind the measurement





Anyone who reads the technical data for loudspeakers will come across values given in hertz (Hz) and kilohertz (kHz).  This is how manufacturers indicate a loudspeaker’s frequency range. The ideal system would have a 20/20 range  – 20Hz and up to 20 kHz which corresponds to what a young, healthy adult can hear (sadly, our ability to hear the upper frequencies diminishes with age).

Pretty neat that we can nail down numbers like this and then make purchases based on clearly defined specs, and there’s one man who deserves the credit for making this a reality: Heinrich Hertz. Before his hard work and ingenuity, Hertz was merely a last name and no one had the slightest idea as to the scientific underpinnings responsible for differences in pitch.

Heinrich Hertz was born in 1857 to a wealthy family in Hamburg in what was then the German Confederation. In 1880, Hertz received his PhD from the University of Berlin and went on to become a professor of physics in Karlsruhe and Bonn.

Hertz was also involved in research with particular interest in the English scientist James Clerk Maxwell’s theory regarding the interaction between electric and magnetic fields. While static on their own, Maxwell belived they could come together to create something dynamic.





James Clerk Maxwell lays the foundation





In 1865, Maxwell published the paper “A Dynamic Theory of the Electromagnetic Field” positing that when electric and magnetic fields converged they took the form of waves moving through space at the speed of light; and further, that light was, in fact, an expression of electromagnetic waves occurring at a specific wavelength. Maxwell also predicted the existence of radio waves.





Today, exposed to so many benevolent and harmful frequencies, its useful to examine the pre-quantum physics science, in the search of clues, to guide us to a proper understanding of the invisible waves around us and comprising us, and more healthy integration with public and private services, communications, industrial, medical and entertainment.





We owe it to ourselves to know the science and know what science and technology is of benefit and what is of harm to ourselves and our environment.





Hertz opens the door to the practical application of electromagnetic fields





Enter
Heinrich Hertz. In 1886, Hertz succeeded in constructing a device that
could prove the existence of electromagnetic waves and was even able to
determine their varying lengths. In later experiments, Hertz managed to
measure the velocity of electromagnetic radiation and discovered it to
be the same as the speed of light, as Maxwell expected. By elucidating
these and other qualities of electromagnetic waves, Hertz opened the
door to research into electromagnetism leading to its practical
application in telegraphs, radios, televisions, and, of course,
loudspeakers.





In loudspeakers, electromagnetism is used to
generate sound that corresponds to the electric charge fed to the system
as alternating current. This is the audio signal, an electrical image
of the accoustic waveform. When the audio signal is passed through the
voice coil, it both creates an electromagnetic field and causes the
direction of this field to change rapidly. This in turn makes the coil
vibrate with a frequency and intensity determined by the audiosignal.
When amplified by a cone, the vibrations create sound waves.





While
generated by an electromagnetic field in a loudspeaker, sound does not
consist of electromagnetic waves, traveling, as it does, much slower
than the speed of light and requiring air as a medium to move. Yet like
electromagnetic waves, sound occurs as a series of sine waves, or
oscillations with a waveform that can be defined as a sine curve, and so
the same measure of frequency – the hertz – can be applied.





Audiophiles
can therefore be doubly grateful to Heinrich Hertz: He pointed the way
towards the practical applications of electromagnet fields and gave us a
way to measure one of the most important aspects of sound.

This is a pretty interesting battle between a man and a Canada goose. The people laughing are funny. They probably have seen that goose fight people before and knew what the man was walking towards the goose already. This goose was full of purpose. Geese sure can chase people and hiss at people. It's funny how he swings a newspaper. You would be laughing a long time after watching this man's situation.

This amazing viral video shows the shocking moments when a Charlotte man is run over by a deer outside a McDonald's. The charging deer knocks the man to the ground before running off. The man took quite a hard hit. It seems that the man did not even see it coming to him. Some people might joke that deer are now getting revenge for people hitting them with cars. What an unfortunate event to happen near McDonald's.

How Beavers Build Dams

Моушн дизайн студия анимации в Киеве



How beavers build dams is pretty interesting. You can sure leave it to beavers. The story of beavers in North America is interesting. See their history, their near extinction, and their current comeback as modern day so-called eco-heroes.

There are various reasons why beavers build dams. Beavers, of course, are compelled to build dams. Much research has revealed that beavers build dams near the sound of rushing water. Of course, they build dams to provide habitat and protection for their young. It may be surprising to some, but not all beavers build dams. They really need an area to build their lodge, like a riverbank. They need food and access to mates. Water allows them to escape from predators.

Amazingly, it takes a beaver about 20 minutes to cut down a 15 cm wide aspen, by gnawing a groove around the trunk in an hourglass shape. A beaver's jaws are so strong and powerful they can cut a 1.5 cm sapling in one bite.

Beavers are pretty intelligent. They are nicknamed, "Nature's engineers." Beavers are responsible for changing the landscape of wherever they live. Beavers had more safety back in the days before they were exterminated for their fur by humans.

Beavers can actually help reduce the risk of dangerous flooding lower down in river systems by building dams and moderating water flow. The modifications made to the streams can raise the water table locally, creating important wetland areas to the benefit of biodiversity.

The Amazing Paradise Flying Snake - Wildest Islands Of Indonesia

Моушн дизайн студия анимации в Киеве



This amazing snake hunts by flying through the air from forest treetops. Some could say that it is not really flying. It is kind of just falling with style. Regular snakes weren’t scary enough. Snakes sure have evolved to different levels. The cameraman created amazing footage here. These flying snakes are indeed impressive.

There are 5 recognized species of flying snake, found from western India to the Indonesian archipelago. Knowledge of their fascinating behavior in the wild is limited. However, they are thought to be highly arboreal, rarely descending from the canopy. The smallest species reach about 2 feet in length and the longest grow to 4 feet.

Cyclists chased by a funny ostrich

Моушн дизайн студия анимации в Киеве



This is interesting in South Africa. The Cape Argus Tour is one of the biggest cycling events in the world. These people are practicing riding on bikes. This big bird is amazing. The ostrich didn't have any problem to keep up at 50km/h and apparently they do 70km/h with no sweat. This is amazing.

An ostrich is a fantastic flightless swift-running African bird with a long neck, long legs, and two toes on each foot. Amazingly, it is the largest living bird, with males reaching an average height of 8 feet (2.5 m).

An ostrich is also a nickname for a person who refuses to face reality or accept facts. For example, "don't be such an ostrich when it comes to security systems."
