Radio is a way to send electromagnetic signals over a long distance, to deliver information from one place to another. A machine that sends radio signals is called a transmitter, while a machine that "picks up" the signals is called a receiver or antenna. A machine that does both jobs is a "transceiver". When radio signals are sent out to many receivers at the same time, it is called a broadcast.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.
3. HISTORY
Marconi was a pioneer of wireless
telegraphy.
The first edition of radio was patented in
1896 by Guglielmo Marconi.
4. GUGLIELMO
MARCONI(1874-1937)
• Guglielmo Marconi was born on April 25, 1874, in
Bologna, Italy.
• Marconi possessed a strong interest in science and
electricity.
• In 1894, he began experimenting with radio waves as
a student at the Livorno Technical Institute.
• Incorporating the earlier scientific work of Heinrich
Hertz and Oliver Lodge in, in electromagnetic waves,
also known as radio waves.
• he was able to develop a basic system of wireless
telegraphy.
• Marconi recognized the value of wireless technology
and was adept in putting the right people together
to invest in it.
5. • Through his experiments in wireless telegraphy,
Marconi developed the first effective system of
radio communication.
• Marconi claimed all the first patents for radio
• In 1897 he received his first patent in England.
6. • On December 12, 1901, he successfully sent
wireless signals across the Atlantic Ocean,
disproving the dominant belief of the Earth's
curvature affecting transmission, and became
the first person to transmit signals across the
Atlantic Ocean.
• Marconi's place in history was forever sealed is
credited as the father and inventor of the radio.
8. THE NOBEL PRIZE IN PHYSICS 1909-
DEVELOPMENT OF WIRELESS
TELEGRAPHY
Guglielmo Marconi was a Nobel Prize-winning physicist and
inventor credited with the ground breaking work necessary
for all future radio technology. Marconi shared with Karl
Braun the 1909 Nobel Prize in Physics.
The Nobel Prize in Physics 1909 was awarded jointly to
Guglielmo Marconi and Karl Ferdinand Braun "in
recognition of their contributions to the development of
wireless telegraphy."
9. PATENTS ON RADIO
• Nikola Tesla tried to prove that he was the
creator of radio.
• In 1893 the inventor Nikola Tesla demonstrated
a wireless radio in St. Louis, Missouri.
• It was Marconi that was awarded the very first
wireless telegraphy patent in England in the
year 1896, securing his spot in radio's history.
• A year later, however, Tesla filed for patents for
his basic radio in the United States.
• His patent request was granted in 1900, four
full years after Marconi's patent was awarded.
• Regardless of who created the very first radio,
on December 12, 1901, Marconi's place in
history was forever sealed when he became the
first person to transmit signals across the
Atlantic Ocean
10. DEVELOPMENTS- 1900-1910’S
• In 1904-1914 the radio had many refinements.
• The radio had enabled a better transmission and reception of the sound that
was being sent.
• It changed the sound of it to a better clearing of the sound due to the
technology they discovered.
• During 1919 the University of Wisconsin-Madison radio station was the first to
ever to broadcast the first human speech.
• The speech went over airwaves and this happened from the discovery of the
human speech through the radio.
11. 1920’S
• In the early 1920 the first ever commercial radio station went on air. It was an
instant success.
• This began a radio revolution called "The Golden Age of Radio.”
• This changed the radio and now it has commercials to listen to in between the
music.
• In the later 1920's the radio completely changed from a bulky device to a nice,
complex that are in wooden cabinets.
• During 1923, Edwin Armstrong invented the superhetrodyne radio and
invented FM radio.
•
13. 1930’S-1940’S
• In 1930 as technology improved the radio was becoming smaller and cheaper
and portable.
• In 1948 the transmitter was a success due to the discovery of Bell Laboratories.
14. 1950’S AND 1960’S
• National News started in 1950s.
• The first transistor radio was unveiled in
1954. The first transistor radio for consumers
was the Regency TR-1.
• In the 1960's the radio was popular and
expanded due to the approval of the technical
standards for the stereophonic radio.
15. 1970’S & 1980’S
• Around the 1980's the radio's speaker's grew with size.
• The radio now has a more clearly sound.
16. 1990’S
• During 1995 the radio's technology became more complex and there were
added features that were attached.
• The technology grew and the radio features and technology changed.
17. 2000’S
• In 2015 there were very compact with large screens and controls.
• In 2016 lots of ideas for making radios for cars and swimming areas and
different places .
