Newton's Laws, G-Forces and the Impact on the Brain Zasady
The Journal of Neurological and Neurosurgical Nursing 2019;8(3):133–137 Pielęgniarstwo Neurologiczne i Neurochirurgiczne THE JOURNAL OF NEUROLOGICAL AND NEUROSURGICAL NURSING /JNNN 2019;8(3):133–137 2019;8(3):133–137 eISSN 2299-0321 ISSN 2084-8021 www.jnnn.pl Review DOI: 10.15225/PNN.2019.8.3.6 Newton’s Laws, G-forces and the Impact on the Brain Zasady Newtona, siła grawitacyjna a ich wpływ na mózg Vicki Evans Royal North Shore Hospital, Sydney, Australia Abstract The thrill to go fast and push boundaries is something that many seek. From John Stapp’s rocket sled at Edwards Air Force Base in the late 1950’s to todays’ Formula 1 drivers, the “need for speed” is broadcast across TV screens weekly. So too are the horror stories of crashes, many at over 300 km/hr. Yet “need for speed” continues. It appears that the higher and faster the rollercoaster, the better. This leads to several questions. How does the brain stand up to speed and G-forces? Do Newton’s Laws still have reference in today’s world? There has been much attention in the general press on the possibility that high G-force roller-coasters are inducing brain injury in riders. However, research does not wholeheartedly support this notion, but rather the risk of brain injury from a rollercoaster is not in the rides, but in the rider — caused by previously undetected brain or neck conditions. That said there is some truth that high G-forces do affect the brain at a chemical and structural level. -
2. Díl – Tryskový Muž Aneb Jaké Je to Létat Jako Pták Poměrně Náročnou Otázkou Pro Mě Bylo, Kterým Zajímavým Projektem Nebo Rekordem Začít
2. díl – Tryskový muž aneb jaké je to létat jako pták Poměrně náročnou otázkou pro mě bylo, kterým zajímavým projektem nebo rekordem začít. Vybírat je opravdu z čeho, protože svět letectví se žene kupředu závratným tempem, takže se ukázalo, že potíží není najít něco, o čem psát, ale naopak vybrat z ohromného množství to, čím začít. Po opravdu náročném rozmýšlení jsem nakonec dospěl k rozhodnutí, že seriál začnu představením toho, co v té nejčistší formě naplňuje odvěkou lidskou touhu létat. Jinak řečeno, začnu hned pěkně zostra. Let ptáků člověka inspiroval odedávna. Důkazy o tom nám poskytují již nejrůznější staré mýty. V průběhu staletí se objevovali vynálezci, kteří navrhovali létajicí aparáty, tu s větším, tu s menším úspěchem. Až konečně bratři Wrightové vstoupili na tu správnou cestu. Jejich následovníci po celém světě zkonstruovali ohromné množství letadel a létajicích zařízení. Žádné z nich však zcela nenaplňovalo onu odvěkou představu o letu, jakým se vyznačují ptáci. Ať už proto, že se člověk vzduchem pohyboval v kovovém obalu, pevně přikurtován k sedačce, jak je tomu v případě letadel, nebo proto, že i když se vzduchem proháněl podobně jako pták, bez nějakých vnějších schránek, bylo to naneštěstí vždy jen jedním směrem, jak by si mohli parašutisté postesknout. Pro dosažení naprosté svobody létání, jak ji zažívají ptáci, by se tedy měly oba tyto přístupy zkombinovat. Zachovat na jedné straně svobodu parašutisty, ale na druhé straně ji doplnit o schopnost plně řídit svůj let, jak jsme na to zvyklí u letadel. Tohoto zadání se chytil švýcarský pilot a dobrodruh – Yves Rossy, známý taktéž jako Jetman, Tryskový muž. -

Forenz: Assessing the Evolution of the Airborne Generation of Thermal Lif Thermal Lift ASSESSING THE EVOLUTION OF THE AIRBORNE GENERATION OF THERMAL LIFT IN AEROSTATS 1783 TO 1883 Thomas Forenz ABSTRACT Lift has been generated thermally in aerostats for 219 years making this the most enduring form of lift generation in lighter-than-air aviation. In the United States over 3000 thermally lifted aerostats, commonly referred to as hot air balloons, were built and flown by an estimated 12,000 licensed balloon pilots in the last decade. The evolution of controlling fire in hot air balloons during the first century of ballooning is the subject of this article. The purpose of this assessment is to separate the development of thermally lifted aerostats from the general history of aerostatics which includes all gas balloons such as hydrogen and helium lifted balloons as well as thermally lifted balloons. -

This file looks at the history of military and civilian balloons and airships, in Lincolnshire and elsewhere, and how those balloons developed from a smoke filled bag to the high-tech hybrid airship of today. This file could not have been created without the help and guidance of a number of organisations and subject matter experts. Three individuals undoubtedly deserve special mention: Mr Mike Credland and Mr Mike Hodgson who have both contributed information and images for you, the visitor to enjoy. Last, but certainly not least, is Mr Brian J. Turpin whose enduring support has added flesh to what were the bare bones of the story we are endeavouring to tell.

Article the Spectacle of Science Aloft
SISSA – International School for Advanced Studies Journal of Science Communication ISSN 1824 – 2049 http://jcom.sissa.it/ Article The spectacle of science aloft Cristina Olivotto Since the first pioneering balloon flight undertaken in France in 1783, aerial ascents became an ordinary show for the citizens of the great European cities until the end of the XIX century. Scientists welcomed balloons as an extraordinary device to explore the aerial ocean and find answers to their questions. At the same time, due to the theatricality of ballooning, sky became a unique stage where science could make an exhibition of itself. Namely, ballooning was not only a scientific device, but a way to communicate science as well. Starting from studies concerning the public facet of aerial ascents and from the reports of the aeronauts themselves, this essay explores the importance of balloon flights in growing the public sphere of science. Also, the reasons that led scientists to exploit “the show of science aloft” (earning funds, public support, dissemination of scientific culture…) will be presented and discussed. Introduction After the first aerial ascent in 1783, several scientists believed that ballooning could become an irreplaceable device to explore the upper atmosphere: the whole XIX century “gave birth to countless endeavours to render the balloon as navigable in air as the ship at sea”.1 From an analysis of the aerial ascents undertaken for scientific purposes and the characters of the scientists who organized and performed them – no more than 10 aeronauts from the beginning of the century to 1875 – an important feature emerges: ballooning – due to its proper nature - became a powerful tool in attiring a general public toward science, more effectively than scientific papers and oral lectures. -
Historical Magazine “Travelling Towards Multicultural Europe” 9
‘Once you have flown, you will walk the earth with your eyes turned skyward, for there you have been, and there you long to return’. Leonardo da Vinci The hot air balloon is the oldest successful human-carrying flight technology. Hot air balloon created on December 14, 1782 by the Montgolfier brothers. On November 21, 1783, in Paris, France, the first flight was performed by Jean-François Pilâtre de Rozier and François Laurent d'Arlandes . Hot air balloons that can be propelled through the air rather than just being pushed along by the wind are known as airships or, thermal airships. In the year 1783, Joseph Montgolfier, his brother, Jacques-Etinenne Montgolfier along with French scientist Pilatre de Rozier invented the modern hot air balloons and on 5th June 1783 it was launched. A hot air balloon consists of a bag called the envelope that is capable of containing heated air. Suspended beneath is a gondola or wicker basket (in some long-distance or high-altitude balloons, a capsule), it carries passengers and (usually) a source of heat, in most cases an open flame. The heated air inside the envelope makes it buoyant since it has a lower density than the relatively cold air outside the envelope. As with all aircraft, hot air balloons cannot fly beyond the atmosphere. First manned flight The brothers Joseph-Michel and Jacques-Etienne Montgolfier developed a hot air balloon in Annonay, Ardeche, France, and demonstrated it publicly on September 19, 1783 with an unmanned flight lasting 10 minutes. After experimenting with unmanned balloons and flights with a rooster,duck and a sheep. -
