Was ist Zeit?

Was ist Zeit - Spektrum der Wissenschaft
[...]
"Zeitnullpunkte und Zeitskalen sind allerdings vollkommen willkürlich und beruhen nur auf praktischen Vereinbarungen. Doch die Zeit als physikalisches Phänomen bleibt. Sie verstreicht, auch ohne dass eine Uhr mitzählt. Wir können sie zwar messen, aber warum schreitet die Zeit beständig, offenbar unaufhaltsam voran? Um dies zu verstehen, lohnt es sich, sie als Dimension des Universums zu betrachten und mit den drei Raumdimensionen zu vergleichen. Hierbei offenbaren sich recht auffällige Unterschiede. Es gibt nur eine Zeitdimension, aber gleich drei Raumdimensionen, nämlich Länge, Breite und Höhe. In den Raumdimensionen können wir uns im Prinzip beliebig bewegen: vor und zurück, nach links und rechts sowie nach oben und unten. Im Unterschied hierzu können wir unsere Bewegungsrichtung bei der Zeit nicht beeinflussen. Noch gravierender ist, dass die Zeit nur eine "Vorwärtsrichtung" erlaubt und dass diese in die Zukunft weist. Insgesamt können wir also in allen drei Raumdimensionen nach Belieben vor- und zurückreisen, aber keine Zeitreise in die Vergangenheit unternehmen."
[...]
"Wenn wir uns dem Universum zuwenden, können wir viel über die Zeit lernen. Zunächst müssen wir feststellen, dass schon der Blick in den Spiegel eine Zeitreise in die Vergangenheit darstellt. Sie glauben das nicht? Das geht so: Licht ist der Informationsträger, der uns von den Gegenständen, die wir betrachten, erreicht und über die Augen in unser Gehirn gelangt, wo wir das Gesehene verarbeiten. Licht ist jedoch nicht unendlich schnell, sondern benötigt Zeit, um sich auszubreiten. Die Lichtgeschwindigkeit beträgt im Vakuum rund eine Milliarde Kilometer pro Stunde. Innerhalb einer Sekunde legt ein Lichtstrahl rund 300 000 Kilometer zurück. Wenn wir also morgens im Bad unser Spiegelbild bewundern, war das Licht vom Objekt unseres Entzückens bis zum Auge schon wenige Nanosekunden unterwegs.
Demnach sehen wir uns nicht, wie wir gerade sind, sondern wie wir vor wenigen Nanosekunden waren. In der Astronomie arten derartige Zeitreisen aus, denn das Licht muss einen viel längeren Weg vom beobachteten Gegenstand bis zu uns zurücklegen. Betrachten wir den Mond, so war das Licht schon rund eine Sekunde von der Mondoberfläche bis zum Auge unterwegs; bei der Sonne sind es schon rund acht Minuten, und das von einem typischen Stern in der Milchstraße ausgesandte Licht benötigt schon einige 100 bis 1000 Jahre. Im Extremfall erreicht uns das Licht aus einer Zeit, in der es unser Sonnensystem noch nicht gab, nämlich dann, wenn es von einer Milliarden Lichtjahre entfernten Galaxie stammt. Was geschieht unterwegs mit diesem Licht, und was können wir daraus über die Zeit lernen?"

Burning Man

The Burning Man Festival. Lots of people have heard of it, many want to go, but, unless you have been there, you won't know what it is all about. Its dusty there. Indeed. It takes place in a desert, not of sand, but of alkali salt. The Black Rock Desert in Nevada, USA has once been a huge, salty lake, which, over time dried out and left salty grounds. Once a year, the last monday of August, for one week only, 50.000 (2012) people gather there to build up a city that is based entirely on creativity of its inhabitants and functions on a gift culture. There is nothing to be sold. Random acts of kindness among the participant do not require you to spent any money. You should only come if you are able to accept and give. There are no requirements, only to bring yourself and express your own personality.

Tickets for attendance are expensive, though. They range from 240 to 420 dollars. Everyone pays as much as they can, there will be those who will happily pay the 420 dollars, while people who dont have as much and still want to come are free to pay less. And yes - that does work.

Black Rock City, as it is called for one week a year, is set up in a half circle. It is well organized and littering is strictly condemned. After each festival, as group of volunteers and organizers will sweep the desert to make sure no sign of humankind will be left over. A map is created that details exactly, where waste has been found and the camps registered at those spaces will receive a warning and might be prevented from participating again if they dont change their behavior.

Everyone who attends is welcome to express themselves, their art, their body, whatever their mind creates. Its an answer to the  question of "What do people do if they are free to do whatever they want?" It seems, when most people are given almost total freedom, they tend to create beauty and make people happy.
Burning Man will make you conscious of the temporary nature of everything, of life, of relationships, of good, and of bad things. All goes by, just to be replaced with something else. And instead of worry or sadness about the passage of things, you are there to celebrate every last moment of it.
Until the man burns. And everyone goes home, just to be wiser and stronger than before. And first and foremost, dirty as hell :D

I want to go :)... after proper preparation, of course.


Burning Man in your Life
The Teafaerie's Views
Stories of the Temple - the spiritual center of Burning Man
The Portals at the Outskirts of the Playa

Meet a first-timer with his brilliant words:
"There is no English translation for the first gift I received at Burning Man. It was not a necklace or a bracelet or other trinkety item of raiment. Instead, it left me exposed, across a stretch of seven extraordinary days on the playa, to both brutal sadness and the gates of personal freedom. It was gifted to me by Mitch, from Chicago, when I told him of my plans to travel to the Northern shores of Brazil.
It was a feeling.
A single word.
Saudade.
As Mitch explained it to me, saudade is a Portuguese word that came to describe a sadness for those who set off on long journeys to sea, or to battle, but never returned. More mysteriously, it’s the anticipation of longing. It’s the duality of envisioning, before you should, a future swamped with nostalgia.
It was with me as I explored the customs and structures of Burning Man, where the most inhospitable place on the planet is transformed, for a fleeting week, into the most creative space in the universe. Saudade was coiled and fused with the ten principles of Burning Man, which inspire participants to carry the playa’s spirit back beyond the mountains and into rebooted lives.
It felt like a warning.
Enjoy this. Preserve this.
I knew Burning Man, like any other party, would come and go, but saudade wanted to know why Black Rock City was the only place on the planet where a civilisation with no bins could produce no litter. Saudade wanted to know if people who came for the party would leave with the message.
Saudade listened as a man called Joe Quirk addressed the crowd at TEDx Black Rock City, envisioning a world unrestricted by borders or visas or work permits. A world lived in floating cities on the sea, equipped to save the environment, cure disease, solve global food shortages and jettison millions out of poverty. In our lifetime? But why not? As Quirk has pointed out, a mere 66 years separated the Wright brothers covering the wings of their first airplane with ‘Pride of the West’ ladies underwear and Neil Armstrong getting moon on his boots.
Burning Man was focused on impermanence. The importance of letting everything go. I was struck, obviously, by the primal value of the wildest party I’d ever seen, but knocked clean cold by the duality of the desert. I saw written on the playa’s Temple deep etchings of regret, remorse, sadness. Saudade. It was written ablaze on a metal sculpture called ‘Phoenix Risen’, built from the scraps of 2011’s Trojan Horse and in homage to Harley Payne, a burner who skydived into last year’s event and died, from heart failure, just a few hours later.
As the sun slanted on the Phoenix, I was approached by a Burning Man volunteer called Bambi. He wanted to know how I felt, as a virgin burner. I told him that I felt a thousand different things, but that I understood. In words I know to be Gandhi’s, I told him that I felt the importance of being the change you want to see in the world. I told him what I had heard about the oceans. We talked about how powerful it could be as a theme. He promised he would plant the idea at the committee’s table.
Between turning my back on the Phoenix Risen and sitting down to watch the temple’s flames, I examined a shrine to Steve Jobs. I read a line from his biography:
“As you get older, your thoughts construct patterns like scaffolding in your mind. You are really etching chemical patterns. In most cases, people get stuck in those patterns, just like grooves in a record, and they never get out of them.”
As the flames took hold, I learnt that you don’t need to blow things up to tear things down.
I said goodbye to my grandmother. I realised a truth about a friend. I saw, clearer than crystal, the parts of me I wanted to leave behind. I tasted my own tears.
I watched it all burn.
Saudade."
(Paul French)

The most astounding Fact about the Universe

"What is the most astounding fact you can share with us about the Universe?"


"The most astounding fact is the knowledge that the atoms that comprise life on Earth the atoms that make up the human body are traceable to the crucibles that cooked light elements into heavy elements in their core under extreme temperatures and pressures. These stars, the high mass ones among them went unstable in their later years they collapsed and then exploded scattering their enriched guts across the galaxy guts made of carbon, nitrogen, oxygen and all the fundamental ingredients of life itself. These ingredients become part of gas cloud that condense, collapse, form the next generation of solar systems stars with orbiting planets, and those planets now have the ingredients for life itself. So that when I look up at the night sky and I know that yes, we are part of this universe, we are in this universe, but perhaps more important than both of those facts is that the Universe is in us. When I reflect on that fact, I look up – many people feel small because they’re small and the Universe is big – but I feel big, because my atoms came from those stars. There’s a level of connectivity. That’s really what you want in life, you want to feel connected, you want to feel relevant you want to feel like a participant in the goings on of activities and events around you That’s precisely what we are, just by being alive…"
Neil deGrasse Tyson, Ph.D. (October 5, 1958)

http://www.youtube.com/watch?v=jt9ucYMWg8M&feature=player_embedded


...and: We know about this! We are aware. We can contemplate the universe without ever having been anywhere else but here. We can infer facts and theories just by observation. We are close to understanding where all of this came from.

Sunshine State

If your university looks like the place you go to in your holidays and you expect a pool and a bar around each next corner - does that help or hamper your education? Universities in the US - and especially those high-class ones like Stanford, the MIT or Berkley are clubs for kids of the rich. An education here costs about 10 to 15.000 dollar per year. That money does go to the universities itself, and it shows. All new buildings of modernist architecture intermix with classical, old-style university-like houses. There is a free shuttle that connects all parts of the uni with the most important landmarks around the area.

More generally, California seems to be a place where beauty calms the mind. In the same way as one puts flowers on the table to smoothen the signals that reach your retina, to make everything look more pretty and friendly, this place on earth seems to be made to please. No surprise that with the sort of climate here all flowers grow to their full beauty, palmtrees naturally intermix with the strangest and most amazing trees and the calming warmth makes everyone smile. Alongside that stunning nature, the laissez-faire attitude of its inhabitants makes everyone in this state feel at ease and peaceful. For sure, there is problems here, and for sure, if I was not so lucky to stay in the rich places of this part of America, I would probably be more attentive to what can go wrong. I am trying hard to see the downside of this. Well, but, if the only problem is an easy chance for a sunburn and being warm every now and then - I could live with that ;) Where else can you go outside and are greeted with a flowerbouquet and smiling people all around. Compare that to England, where the run down cities make you question the common sense of beauty and you forget a little bit how much your mood enhances just by seeing something colourful and beautiful.


"Live in New York City once, but leave before it makes you hard. Live in Northern California once, but leave before it makes you soft. Travel." ("Sunscreen" by Baz Luhrman)


I wonder why it would make you soft. Is being placed into a bubble bad if you are happy with it? For sure, just eating toast bread makes your teeth go soft, and you get caries more often which will result in pain and loss of teeth. What does becoming soft as a person mean and will it prevent you from coping with life's challenges? Is that something we need, being hard to stand against the world? What does that idea say about us as a society?

We are Free

THIS is the most amazing time and place to be alive. For sure, there have been more, other times to live in, wild, or romantic, violent, changing and boring. However, with the right state of mind and due to our youth, this is the best time. For us. Following generations will claim the same if they are lucky, and we will shake our heads and remember these days. They are probably never coming back, but they will evolve, as we do. We learn. We listen. We create and destroy. We feel, we hope, we love. Continuously. Even through hardships and rough patches, even when when we loose or fail. This is the most amazing time to be alive. We can apprachiate it while it lasts because we are conscious beings, we evaluate and we search for feedback, try to compare our views to others and experience being special all the time. This is of course a very personal sight, as everyone is special in his or her head. If we didnt have this why would we work for ourselves?

This is the most amazing time to be alive. Not the sixties in which every thought was able to light sparks all around. Not the time before where the world still seemed secure. Not the time after which was full of new inventions. It is now. And here. That place is not a location, it is a headspace. We are getting out of our teenage years and we find our place, our niche in which we can be brilliant. We are free.

Living this life with this head and mind makes us creators, stars in our own movie. With our words we blow life into concepts, and into plans and into a life's history. With the right kind of eyes we can see where we came from and where we are going.

THIS is the most exciting possible time to be alive.

"To be an adult means, among other things, to see one’s own life in continuous perspective, both in retrospect and prospect. By accepting some definition as to who he is, usually on the basis of a function in an economy, a place in the sequence of generations, and a status in the structure of society, the adult is able to selectively reconstruct his past in such a way that, step for step, it seems to have planned him, or better, he seems to have planned it. In this sense, psychologically we do choose our parents, our family history, and the history of our kings, heroes, and gods. By making them our own, we maneuver ourselves into the inner position of proprietors, of creators." Erikson, 1987

Pale blue dot

The world is a big empty place. 3/4 of it supposedly isnt even populated. At least, that's what it looks like from the airplane I am on, destination San Francisco. It started in Amsterdam, went straight up to Scandinavia, over Iceland, then Canada.

The seat next to me is free which of course is very fortunate. While the plane I am on is huge, so huge I was surprised it could fly, each individual on it does not have too much space at his or her disposal.

The service here, as was pointed out to me before, indeed is at a completely different level. There is two meals, water and juice are free and they come around ever so often to bring you snacks or warm towels. Every seat has a little personal screen on which one can chose their own entertainment program, with music, newschannels, games, the newest movies, recent ones and all time classics (think, Mrs. Doubtfire). Even writing emails and texts as well as making phone calls is possible (for a little extra money, of course..).

By the way, a warmer climate wouldnt be too bad for the world by the looks of it, at least, big parts of it would become habitable then. Of course, I know, climate changes are bad etc., but seeing our planet from an 11 km distance doesnt make it look so fragile as scientists propose. It is way more strong than we are, and if we annoy it, it will probably just extinct us. The earth will continue to exist, changed or unchanged. Have a look at volcanoes, then you will know what I mean. Take me with you? ;)

Life Changes

Oh yes, it does.
Suddenly. It hits you and then you are a new person. Someone with new hope, with a different view on life. Someone with a perspective that is enhanced, broadened from what seemed to be quite narrow before. There is this new person and I dont need to hide so much anymore.
I am afraid to read too much into all of this, while everything tells me I can if that is who I am... This, while new, seems so familiar, so comfortable, so natural. If, by personality, I am a person who is fast to find deep significance in what happens to her, that trait is encouraged now by the knowledge that the other person involved thinks along these same lines. If I find myself thinking about something specific, and when I share it, that gets rewarded by the confirmation that those same thoughts have been crossing the other persons mind, too. Why is it that things change so quickly? Where is the downside? Why can I not just be happy, without worrying, without keeping myself braced for the possibility that this is all unreal, that the dream house of cards just falls apart, leaving me being laughed at by some undefined entity of life? The interesting thing is, that I - again - am not alone with this fear and those worries. We do share them and while they persist, we give each other the confirmation, that so far, all is true and real. Its like getting glasses when you did not know you needed them. You did see fine before, but suddenly, a whole new perspective opens to you and you cant understand how you could not have missed it before.

Oh happy day...

 Habe endlich das doofe Proposal abgegeben und hoffe jetzt darauf das ich nicht zuviel ändern muss..wie ich das entspannte Gefühl aber kenne ist das jetzt nur die Ruhe vor dem Sturm ;)
Ansonsten hab ich am Wochenende mal wieder nette Leute kennengelernt und trotz Druck wegen dem Proposal den Sonntag so verbracht wie ich es schon länger mal wieder gern wollte - halbwegs im Bett :-D Das allerdings auch, weil es saukalt war und ich nur meine kleine tapfere Heizung bei mir hatte da das allgemeine System des Hauses ausgefallen war..
Ich hoffe, alles entwickelt sich so wie es soll..:)

Fliegen on ice

Das Flugzeug mit dem ich gerade von Amsterdam (nach erfolgreicher Präsentation meines Doktorprojektes in Belgien) zurück nach Bristol geflogen bin musste vor dem Flug noch enteist werden und weil das Fahrzeug das das sonst macht Probleme hatte mussten wir da hinfahren..Ich bin ein ziemlicher Flughafen und FlugzeugNerd (wegen meinem FlughafenFeuerwehrChefVater und auch so schon), deswegen war das jetzt grade ziemlich cool...Amsterdam ist ein riesen Flughafen, und es war dunkel, deswegen war der Flughafen ein einziges Lichtermeer. D.h wir sind jetzt 10 Minuten lang da durch gefahren und wurden dann in so einer Station mit Enteisungszeug besprüht..Ich sass hinterm Flügel direkt beim Triebwerk - und hatte mich eigentlich geärgert weil so der Fensterplatz nicht wirklich was bringt, aber dadurch hab ich die ganze Prozedur aus nächster Nähe gesehen.. Alles kommt wie es soll :) Das Flugzeug hat alles an Klappen und Landetragflächen ausgefahren was es hatte damit das Zeug überall drüberlaufen konnte und mich hätts ja schon fast nicht mehr gewundert wenn es mit den Flügeln geschlagen und sich dann wie eine nasse Ente geschüttelt hätte :-D Jedenfalls wurde dann alles wieder eingefahren und wir sind wieder zurückgefahren und abgeflogen...all das zu einer Synphonie aus Marina & the Diamonds, The Postal Service & Supertramp.. Life is good  :)
