The Beginners Guide To Radio Presentation

SARA Annual Conference 2018

Another type of radio scope, SuperSID, allows you to collect real data from the ionosphere resulting from solar activity. You can then send this data to the University of Sanford database. The Astronomical League has a radio astronomy observing program, and that can guide you in a disciplined approach. As you explore radio astronomy, reading and watching videos on the subject will help understand more about the field.

A good starting point for a radio telescope is to check out this page on the SARA website.

A very good video presentation on microwave antenna demonstrations is available on the SARA site at: Also located on the SARA main webpage menu bar is a link for projects: Two o ther good primers are: Attending a SARA conference will also help in your efforts to learn more about radio astronomy. The annual conference at NRAO in Greenbank, WV provides instruction on a foot radio scope that is available for personal use throughout the conference. An instruction class is given on the first day of the conference so that you can use the device immediately.

Skynet University offers an online class that allows use of a 20 meter radio telescope dish. Information of the class is found at: Use of Skynet is also a complimentary benefit in some local astronomy clubs, and for a small fee, is also available to individuals. Local astronomy clubs might also have radio astronomy instrumentation for your use. Once a beginner identifies a radio telescope and project, one needs to understand what is being observed.

Radio astronomy is more than just observing. Equipment, instruments, and confounding factors are all important in understanding observational features as well as observational errors. Visual astronomy is much more simple in this respect. Even with access to radio telescopes, it is not a simple process of viewing something with the human eye.

Radio telescope sensitivity is a measure of the relationship between the signal and the noise.

more on this story

The signal is the power detected by the telescope from the astronomical phenomena. The noise is mostly thermal from electronics but also ground radiation entering the feed horn and the cosmic microwave background and other interference.

The dominant sources seen in the radio sky are the Sun, supernova remnants, radio galaxies, the Milky way. Sources as bright as 1 Jy are relatively rare. Whereas the limiting magnitude of an optical telescope is easily determined, the limiting sensitivity of a radio astronomical receiver is much more complicated. The gain and noise figure of the LNA are important, as well as the noise pollution in the local vicinity.

There are nearly eight orders of magnitude between the strongest and weakest sources that an amateur might detect. The level of equipment sophistication required to detect these sources will therefore vary considerably — from a standard communications receiver to detect solar bursts, to special temperature controlled receivers and preamplifiers to detect galaxies. Almost all amateurs begin by detecting the Sun. This is easy to do. But before Game of Thrones was even a series, House Targaryen was toppled by a cabal of sweaty northern feudal lords, headed, naturally, by Mark Addy and Sean Bean.

Robert Baratheon Addy then seized the Iron Throne of Westeros, wed smouldering snootyboots Cersei Lena Headey of the fabulously wealthy House Lannister, thought he'd sired an heir more on that later , chose Sean Bean's Lord Eddard Stark as his hand ie chief administrator and then promptly died, plunging Westeros into renewed civil war. Who, as war rages, will wrest control of the Iron Throne — the Lannisters, the Starks, or the exiled Targaryens, who sensibly forged an alliance with the thoroughly unpleasant and sexually unreconstructed warrior-nomads the Dothrakis, and have found their secret weapon, dragons, aren't extinct?

Or the fun-sounding Balon Greyjoy, lord paramount of the grim Iron Islands? Or will equally funless Stannis Baratheon Stephen Dillane successfully press House Baratheon's claims, aided by a witch with surely anachronistic hair extensions? The sea battle of the Blackwater that dominated season two appeared to have cemented the Lannister claim, though only a fool would plot the looming third series without challenging that supposition.

Let's cut to the chase. What King Robert didn't know is that his son Joffrey, who succeeded him, is not his son. Evil-but-gorgeous Cersei has long been in a secret incestuous relationship with her no-less-evil-and-similarly-gorgeous brother Jaime, played by Nikolaj Coster-Waldau with an eye to being as hunky and wisecracking as Errol Flynn in tights or Flynn Rider in Tangled.

The chief fruit of their taboo-busting canoodling is mad Joffrey not to be confused with Madhur Jaffrey , who now rules from Westeros's capital King's Landing with a disregard for posterity not seen since Shakespeare made Richard III all hump and hubris. He's aided by slimy counsellor Petyr Baelish Aidan Gillen — natch and eunuch adviser Varys Conleth Hill who, happily, has achieved closure over the trauma around his missing crown jewels.

How evil are Cersei and Jaime, you ask? Cersei now keeps tabs on her son Joffrey's misrule, while Jaime, aka "Kingslayer" for his swordsmanship, has escaped imprisonment by House Stark and roams the country with 7ft swordswoman Brienne of Tarth, with whom he's surely destined to fight to the death or get it on — perhaps both at the same time, in a grisly liebestod. The incestuous couple's younger brother is Game of Thrones' most compelling character.

Tyrion is a randy, dissolute, appealing dwarf compelled by circumstance to become Machiavellian and military, despite his understandable preference for bedroom pleasures over going toe-to-toe with Westeros's many sword-wielding nutjobs. Peter Dinklage has won awards for his suave Tyrion — though if that's an English accent, it's not one with which England has been familiar hitherto. He hates Tyrion because his queen died giving birth to his son. Sylvia Plath wrote a poem about his type.

When will Sean Bean make it to the last reel? Not in The Lord of the Rings, and not here. What Kenny was to South Park, so Bean is to dramatic medieval franchises. His execution by evil King Joffrey's lickspittles after being fitted up for treason was one of season one's shocking moments.

How could the show's creators terminate the central character? Especially as Joffrey has made a queen of Eddard's understandably troubled elder daughter, Sansa? Eddard's death propelled the plot forward. In quick succession, his son Robb Stark set himself up as king of the north and mustered an army to topple the increasingly bonkers Joffrey in the south, and Robb's sister Arya Maisie Williams fled the King's Landing court. Arya finally pitched up in Tywin Lannister's fastness, where she has become not just a poppet of a renegade tyro swordswoman but her dad's enemy's trainee cupbearer.

Will she exact revenge? Robb's mum Catelyn Michelle Fairley , meanwhile, is engaged on diplomatic missions to secure alliances for Robb's claim to the throne. Good luck with that, former Mrs Bean.
