Baird : The Wonder Of Television
The following article was scanned by me from
"The Wonder Encyclopedia For Children"
Apart from minor adjustments to layout and removal of page references it is verbatim.
I present it here as a view from the past, when television was a brand new scientific achievement being presented as a new wonder to children and using the latest photographic illustration techniques.
John Logie Baird describes broadcast television in his own words.
THE WONDER OF TELEVISION
Electric Eyes that Scan the World
By J. L. BAIRD
Now here’s an interesting chap.
The Göttingen Academy of Sciences  was founded in 1751 with Albrecht von Haller (1708 – 1777)  as the main driving force in the setting it up. He had very definite views on what an academy should be. The historian Morris Kline writes:–
The Royal Mail has launched a Special issue commemorating the 350th Anniversary of The Royal Society. Ten specially-commissioned stamps have been issued showing some of the most famous scientist in the Royal Society's long history.
The question is... who are they? (and no peeking
at the Royal Mail website!)
An Argument For Cross-Disciplinary Studies
Lack of experience diminishes our power of taking a comprehensive view of the admitted facts. Hence those who dwell in intimate association with nature and its phenomena grow more and more able to formulate, as the foundations of their theories, principles such as to admit of a wide and coherent development: while those rendered unobservant of the facts by their devotion to abstract discussions are too ready to dogmatize on the basis of a few observations.'On Generation and Corruption'Aristotle
(384 BC – 322 BC)
Why did the Babylonians and the Greeks approach astronomy so differently? In my last post
I quoted Toulmin and Goodfield from their history of dynamics and astronomy, The Fabric of the Heavens
, where they argue that the Babylonians, because of their careful record keeping and math skills, could make excellent astronomical predictions, but they couldn't explain why those predictions worked. The Greeks on the other had were obsessed with explanation and theory, and were for a long time relatively bad at astronomical prediction.
There is a plaque on the south side of Trafalgar Square, just behind the statue of Charles I, that is the reference point from which all distances from London are measured. However, there is a far more intriguing plaque of scientific interest that is also associated with a tale of official incompetence and disaster.
Between the January 1589 and the spring of 1590, at Helmstedt, Giordano Bruno wrote "The Lulliana Medicine”.
This work consists of a practical application of the Lullian System in the medical astrology. The text incorporate large sections of Explanatio Compendiosaque Applicatio Artis Illuminati Doctoris Magistri Raymundi Lulli (1235-1315), edited by the Franciscan Bernard de Lavinheta (c.1517).
The work opens with the premise that health is determined by the balance of four elements, fire hot and dry, the air hot and humid, the water cold and wet and the earth dry and warm. Regarding the astrological studies applied to the medical art, Bruno gave to the world a vision of nature alive full of magic and spirituality.
In popular culture the Greek Muses are seen as representations of artistic inspiration. Writers, and especially poets, are keen to express their mysterious source of insights as a territory inhabited by their muse. Dante, feeling fragile and forlorn as he enters the Inferno laments, “O Muses, O high genius, aid me now!” This may all seem a bit of classical allegory; harmless but slightly anachronistic for our age. However, I think the Muses are symbols of something far more important.
Let's firstly look at a list of the nine Muses and their respective arts:
Calliope - Epic poetry
Clio - History
Erato - Lyric poetry
Euterpe - Music
Melpomene - Tragedy
Polyhymnia - Choral poetry
Terpsichore - Dance
Thalia - Comedy
You're living as part of a small band of hunter-gatherers 30,000 years ago in what will later become France. How do you explain the fact that a stone, when dropped, falls to the earth? How do you even begin to think about gravity?
People sometimes wrinkle their noses when, in the context of explaining the meaning of the word 'theory' in science, you talk about the 'theory of gravity'. Gravity is a fact, isn't it? But from our 21st century perspective, we take too much of 2000 years of theoretical developments for granted. So try to imagine how you would even begin to think about gravity if you were living in a cave 30,000 years ago.
With the first decade of the millennium coming to a close, it is time to take stock. What have 'The Noughties' brought us in terms of scientific advances?
