Warto Mieć Marzenia: Solar Impulse i Bertrand Piccard

leave a comment »

A gdyby tak spróbować odbyć nocny lot samolotem zasilanym…słońcem? Na taki, pozornie szalony pomysł wpadł dr Bertrand Piccard, szwajcarski psychiatra i baloniarz. W 1999 r. Piccard wraz Brianem Jones’em jako pierwsi z sukcesem odbyli lot balonem dookoła ziemi, nie robiąc przy tym ani jednek przystanku. w 2004 r. Piccard ogłosił, że chce oblecieć świat samolotem zasilanym słońcem. I nad realizacją tego marzenia pracował przez ostatnie sześć lat. W kwietniu jego samolot o rozpiętości skrzydeł takiej, jaką ma Boeing 747 oraz wadze małego samochodu pomyślnie odbył półtoragodzinny lot. To był jednak tylko wstęp do kolejnej wielkiej próby Solar Impulse, która zakończyła się sukcesem wczoraj (8 lipca). Zasilany 12 tysiącami paneli słonecznych samolot odbył 26 godzinny lot, unosząc się w powietrzu nawet po zapadnięciu zmroku. Pilotowany przez 56-letniego bylego szwajcarskiego pilota-oblatywacza, André Borschbera samolot, wzbił się na wysokość ok. 8,5 tys. metrów nad poziomem morza i poruszał się ze średnią prędkością blisko 42 km na godzinę. Podczas swojego nocnego lotu Borschber musiał znieść chłód, ścisk małego kadłuba oraz turbulencje. Ale dał radę. A samolot, który nie zużył pdoczas lotu ani kropli paliwa – też.
“Bravo André! właśnie udowodniłeś, że to, o czym amrzylem od 11 lat, jest możliwe” – wykrzyknął Piccard, pomysłodawca porjektu w chwili, gdy Solar Impulse HB-SIA dotknął ziemi.
A tutaj niezwykle inspirujące wystąpienie Bertranda, jakie wygłosił podczas konferencji TED.

Sztuczne życie raz!

with one comment

No i Craig Venter dopiął swego. Przynajmniej tak wynika z publikacji w piątkowym science. Po 15 latach prac naukowcom udało się stworzyć coś, co zakrawa na miano syntetycznego życia. Badacze wpierw stworzyli genom bakterii (dokładnie Mycoplasmy mycoides) z wcześniej zsyntetyzowanych kawałków, a następnie umieścili go w “opakowaniu” z wypatroszonej bakterii pokrewnego gatunku – Mycoplasma capricolum. Tak powstały twór zachowywał się jak M. mycoides – produkował charakterystyczne białka oraz podlegał podziałom.
Jak proponują autorzy pracy, tego rodzaju syntetyczne bakterie mogłyby się przydać np. do produkcji środków chemicznych, leków, paliwa czy wreszcie można by je wykorzystywać do niwelowania substancji szkodliwych dla środowiska.
Czy plany naukowców się powiodą? We’ll see (choć patrząc na biografię Ventera, to ów człowiek raczej konsekwentnie realizuje swoje plany)

Więcej o dokonaniu można poczytać np. w artykule Piotra Kościelniaka z Rzeczpospolitej.

Adopt a Star and Why I Have Bought a Site on

leave a comment »

keplerWant to have a star form the sky? Well, nothing simpler. As the New Scientist writes, with the new project called Pale Blue Dot (name comes after how Carl Sagan used to call our own planet)  You can well, not buy,  but adopt a star. With this quite unique programme a non-profit organisation is raising money for analysing data collected during the NASA’s planet-hunting Kepler Mission. For 10 dollars you will get a chance to pick one of more than 100 000 stars and   put a small flag on the one chosen (all adopted stars are presented on Google Sky ). If there would be any discovery related to your star, you will be informed about it asap.

What do You think about it? I think it is just simple great! First, with small money you are helping scientists who really need cash and are doing some amazing stuff. Second –  isn’t it just a great fun to adopt a star? Personally, I would be very keen on having one or two cosmic pupils under my care.

For this same reason – purely childish fun – some time ago I have bought …a spot on a Moon. Well, being precise I have bought a certificate of ownership of a football pitch size lot. Yes, you can call me a total space-geek or a typical victim of too much Star Wars watching but what the hell – I am a happy owner of some little piece of Silver Globe. So if I will really get bored with Earth life I will have some place to run 🙂

40 years ago…

leave a comment »

NASAMOONLANDING
OK, it won’t be a surprising post. But I think it is impossible to skip some subjects and pretend they don’t exist. Ladies and Gentlemen – 40 years ago we have stepped on the moon for the first time. Now we know that Apollo 11 mission and the whole space race thing was more for show-off than for science. Many argue that overall cost of the Moon expeditions was totally disproportionate to the amount of scientific knowledge. And of course some still don’t believe at Moon landing at all and that those brillinat pictures were made during some big show made by Hollywood FX specialist.

Was it good or bad that we have decided to hit the Moon? Did that expedition and many afterwards have any sense at all? IMHO You can’t be judge here. As far as my opinion is concern – I don’t perceive the Apollo 11 mission as a technology triumph or the final proof of human courage and braveness.
For me the space programs – the old one and the one runnig now – are the essence of very human characteristic – curiosity. And in my opinion appeasing of this curiosity is a fine justification for all our cosmic ideas.

In the 40th Anniversary of the Moon landing, when Buzz Aldrin and Neil Armstrong were fighting to stuck US flag in the powdery surface of the Silver Globe, 13 astronauts are hanging somewhere above, on the board of ISS, with their toilet broken and food flying around them.

I am wondering: What were people thinking 40 years ago, watching Armstrong in TV? That in 2009 average American family would spend each summer holidays in Space? Or at least that the Moon will be a popular spot for getting marry?

Well, it seems that Space has occurred to be more harsh to conquer that we have previously And it is still a huge challenge for us to go there with no bad surprises and live and work there as we would do on Earth.

But IMHO, even it occurred to be harder that we have suspected, we should be keeping trying. Why? Just to prove that we are human – curious the world around us, keen on going where no one has been before and somehow irrational in our dreams.

And for dessert – some nice present from NASA

PS
I would like to apologize that I haven’t been here for so long. Life, You know. But I promise to be better and write at least every 2 days.

Join the first scientific experiment on Twitter

leave a comment »

Twitter as an experimental tool?
Why not!
Today Richard Wiseman has announced  on his blog the official start of the First Scientific Exeperiment on Twitter. It is being organized togather with the New Scientist. The idea (making long thing short) is to chceck if people can guess once localization. Each day on 3 PM (GMT) Richard will post a tweet and all his followers are  asked to guess where the hell he is.

Richard writes: “If the majority of people select the correct target then the trial will count as a hit, otherwise it will count as a miss. There will be trials at 3pm on Tuesday, Wednesday, Thursday and Friday this week. Three or more hits in four trials will be seen as supporting the existence of extrasensory perception.”

To achieve valid results, Richard need thousnads of people joining him.

To participate, simply follow him on Twitter.

All (wrong) about Ida – great discovery or great misunderstanding?

leave a comment »

UPDATE:Thanks to the New Scientist Ida can now enjoy her scientific name formally and legally!

FROM THE SHORT SHARP SCIENCE blog:
“Since I spoke to the ICZN about the name Darwinius masillae, the journal has come up with an emergency fix – they’ve printed out 50 copies of the paper. They’re on sale for $10 each from the PLoS offices in San Francisco. Apparently the commissioners are now happy and the name is now valid. Phew.” Agree – phew!

————

Well well, lat week we’ve all hear about the discovery of fossil nicknamed Ida – a skeleton which supposed to belong to the animal being a IdaColourNewTeasermissing link in human evolution. And all this right in 200th birthday of Charles Darwin, which we are celebrating this year. Cool, isn’t?

Unfortunately, Ida occures to be quite problematic girl. Fossil. Whatever. First, there are some strong doubts wheter Ida really is a missing link.

Later the Wall Street Journal has written that the date of the announcement of the discovery was enforced by the TV producers.

And noww, as the New Scientist’s blog “Short Sharp Science” reports, there are even doubts wheter Ida can keep its scientific name. Formally Ida has been named  Darwinius masillae, in honour of Charles Darwin’s 200th birthday. Paper about its discovery has been published in the online science journal “PLoS ONE”.

“But the rules set by the International Commission on Zoological Nomenclature (ICZN) require species names to be published in print before they can be formally allocated.” – the blog reminds.
