Radios first came about in the 19th century, when people discovered that electromagnetic waves could spread through space. Although there were many discoveries and inventors leading up to the radio that we have today, some big names are probably more recognizable than others. Nicola Tesla, Thomas Edison and Heinrich Rudolf Hertz were all to thank for this invention. Guglielmo Marconi may not be so familiar, but he was the one who built the commercial wireless telegraphy system in 1894 and is due most of the credit of the development of today’s radio. He used Hertzian waves to produce a useful communication system that could transmit signals up to 2 miles. He later won the Nobel Prize in Physics and is celebrated as the inventor to commercialize radio.
The number of advertised job positions in Science and Technology has gone up 22 percent in the last year, driven largely by the increased emphasis on STEM skills in sectors such as mining and engineering. The mining, resources and energy, trades and services, engineering, government and defence jobs saw the biggest jumps in job offer numbers according to Seek.com.au. The current competition between engineers and IT qualified Australians is fierce. And, it is evident that we do not have enough skilled workers to fill these roles.
