Brompton Friday's Test Drive
Try Brompton is a Brompton experience ride for those considering purchasing a Brompton. The purpose of this ride is to deepen your understanding of Brompton bikes, ride courses designed to fully enjoy Bromptons, rediscover the city, experience new ways to enjoy it, and experience the lifestyle that comes with owning a Brompton. We guide participants through folding techniques and shifting the internal gear hub—a common source of confusion for first-time riders—while riding. By comparing different bikes, we help riders deeply understand each model's characteristics, supporting them in making an informed choice and purchase.

Chinese 中文 Chinesisch/German 德语 Deutsch Meetup! (Every 2 Weeks!)
Hey fellow Dragons!
++++++++ Interested in Chinese/German? ++++++++
Learning Chinese/German and need to practice or find language-tandem partners?
Interested in cultural exchange?
Want to meet awesome internationals?
…Or just want to get tips on where to find good Chinese food in Berlin?
Whatever the reason, come join us! The more the merrier: such is the Chinese way!
++++++++++++++++ Our meetup structure ++++++++++++++++
Our meetup is relatively unstructured. Groups often form organically and evolve and move throughout the evening consisting of members learning Chinese/German, members who are fluent/native, and the rest who are here to socialize in whatever language they're comfortable with and jumping into whichever conversation they find themselves in.
We try our best to fulfil everyone's expectations so we can all benefit from the meetup and have a good time; if you have any suggestions or ideas (such as outings!) please don't hesitate to let us know! :)
+++ No time on Thursday's? +++
We meet every second Thursday, but we sometimes have other events, which are not regular and occur on different days/at different locations. Stay tuned for announcements!
Looking forward to seeing old friends and making new ones :)

Philosophie 2.0 - spielerisch klug durch maximale Klarheit
Mit dem Titel "Philosophie 2.0" wird nicht zu viel versprochen.
Nicht alles was mit 'Philosophie' bezeichnet wird, hat damit auch zu tun.
Das gilt allgemein.
Wörter werden zu oft nicht präzise gebraucht, aber wenn man alles mit beliebigen Wörtern bezeichnen würde, könnte man nichts mehr genau verstehen, könnte nichts mehr genau begreifen. Also blieben die Irrtümer bestehen. Das hätte mit Philosophie aber definitiv nichts mehr zu tun.
Was also ist das Gegenteil belanglos-vieldeutigen Wörterverdehens mit hochassoziativen Sprüngen bei denen allerlei übersehen wird und ergo das Wesentliche nicht mehr als solches klar erkannt werden kann?
Maximal exakte Begriffsklärung.
Und das geht!
Das geht über einen systematischen Aufbau aller Kategorien - gestützt über einen Algorithmus, welcher Kategorienfehler automatisch vermeidet und mithilft, das Ganze im Blick zu behalten.
Dass dies für uns Personen gar nicht so einfach ist, sieht man daran, dass jede Person (auch Du) irgendwann irgendwelchen Irrtümern aufgesessen ist.
Jede Person, die sich also für irgendetwas ernsthaft (nicht wegen blanglosem Amüsement, oder wegen ideologischer Rechthaberei) interessiert und ergo dafür offen ist seine Auffassungen weiterzuentwickeln, ist bei dieser Veranstaltung goldrichtig.
Ablauf:
Bei unserer Diskussion geht es dabei nicht um irgendein festes Thema, sondern jeder schreibt ein Wort in seinem Interessengebiet auf einen Zettel und wir ziehen diese paarweise für je eine Runde.
Die beiden Wörter haben gemeinsame Kategorien, aber es gibt auch Unterschiede.
Wer diese nicht alle kennt, kann nicht behaupten, dass er tatsächlich begriffen hat, wovon er meint, dass es ihn interessiere; dass er definitiv wüsste wovon er spricht.
Dieses Problem hatte schon Sokrates erkannt. Nur haben wir jetzt einen Algorithmus, welcher zu absoluter Genauigkeit verhilft um diese Irrtümer loszuwerden. Daher 'Philosophie 2.0'.
Siehe dem Bild oben werfen wir die Bedeutung (die Menge aller Kategorien einer Begrifflichkeit) per Beamer an die Wand.
Wir sind nicht in der Schule, d.h. es gibt keinen Zeitdruck, keine Noten, keinen Wettbewerb und keine Profilierungsmotive, sondern jeder hat alle Zeit der Welt um über die schematisch dargestellte Bedeutung nachzudenken - und diese zu hinterfragen.
Die grafisch dargestellten Bedeutungen des Algorithmus sind nicht perfekt.
Es geht nicht darum irgendetwas zu akzeptieren, sondern andersherum: die Bedeutung anzugreifen und zu verbessern.
Jeder kann sie ändern!
Die Diskussion ist also eröffnet. Jeder muss Gründe angeben.
"Kann ein Walfisch ein Wellensittich sein?"
\~> Natürlich nicht, denn Säugetiere sind keine Vögel.
"Kann ein Fenster ein Getränk sein?"
\~> Jeder weis, das ist unmöglich, denn Festkörper sind keine Flüssigkeiten.
"Kann eine Demokratie eine Republik sein?"
"Kann eine Vermutung eine Meinung sein?"
"Ist etwas zu begreifen das Selbe wie etwas zu verstehen?"
Nichts regt dermaßen zum nachdenken an wie die Bedeutung der Begrifflichkeiten algorithmisch stabilisiert zu systematisieren.
Und wenn wir uns nicht einig werden?
Die Diskussion läuft auch nach der Veranstaltung weiter. Jeder kann online von zuhause die Diskussion fortführen - mit dem selben mitdenkenden Algorithmus.
Man könnte sagen, es sei ein neues Gesellschaftsspiel - ohne Wettkampf, sondern in kollektiver Bereicherung an Klarheit, von der alle gigantisch profitieren, obschon jeder nur einen sehr kleinen Teil beiträgt.
Das "Spiel" funktioniert auch mehrsprachig, denn der platonische Raum der Begrifflichkeiten ist der eindeutige Raum, auf den das Vokabular einer Sprache nur referiert.
Man kann auch von Zuhause aus online mitmachen. Den Zugang können wir dann über die Kommentare hier organisieren.
Bring deinen Laptop mit, dann wird es einfacher...
Dieses Spiel macht klug:
Schach trainiert zwar das Konzentrationsvermögen, hat aber mit der Wirklichkeit nichts zu tun.
Dieses Spiel hingegen schon, denn genau mitdenken zu können setzt voraus genau zu unterscheiden.
Wer die Bedeutung der Wörter sauber ausdifferenziert wird immer klüger.
Mach mit!
Chinese New Year Dinner Party
Dear Dragons,
The year of the horse is just around the corner.
To celebrate, we're having a dinner party at a Chinese restaurant.
What will the year of the horse bring? 马到成功, 马上有钱, 马上升官发财, are just a few blessings that come to mind.
Ready to hit the ground running in the new year with a tummy full of delicious Chinese food (preferably after the food has digested... you get the picture) and good company? We are happy to celebrate with you!
Sincerely,
Yimu and Xuedi
