How the world works

Your science by birthday

NEBO reads the whole birth chart, not only the Sun. Here’s where the model sends people most often, and which signs land in each place more than others.

1Your birthday
Day, month, year. Add a birth time if you know it and you get a rising sign too.
2Your whole chart
Sun, Moon, Mercury, Venus, Mars. Not just the one sign you read in horoscopes.
3Your character
Matched on your whole trait profile, plus your science and the famous people who got the same.

Each sign is tinted with the group it lands in most. Your Moon, Mars and the rest of your chart can still move you.

Experimental physicsTaurusVirgoCapricorn
You test ideas in practice: lasers, measurements and the patience to repeat an experiment for the hundredth time. Brains and humanity are in rare balance in you.
The real worldAriesLeoSagittarius
You don't quote theorems, but you understand people better than any genius. Social smarts, humor and the knack for dragging scientists into real life.
Neuroscience & medicineGeminiAquariusPisces
You're curious how thoughts, feelings and decisions work. A scientist's precision and a bluntness that surprises at first and then wins people over.
MicrobiologyAriesCapricorn
Tiny organisms, big discoveries and even bigger ambitions. Organization, persistence and character: the whole crew knows it's better not to make you mad.
Theoretical physicsTaurusGeminiAquarius
You think in big ideas and see patterns where others see chaos. Logic, memory and total confidence that you're right: now you just have to explain it to the rest of humanity.
AstrophysicsCancerScorpioPisces
You look at the stars and see stories. Dreaminess, imagination and a big heart: you can talk about black holes for hours, as long as someone's listening.

Questions

The Big Bang Theory by birthday: what people ask

The Big Bang Theory zodiac signs: which character is each sign?

Aries: Howard Wolowitz. Taurus: Sheldon Cooper. Gemini: Amy Farrah Fowler. Cancer: Raj Koothrappali. Leo: Wil Wheaton. Virgo: Leonard Hofstadter. Libra: Amy Farrah Fowler. Scorpio: Raj Koothrappali. Sagittarius: Penny. Capricorn: Bernadette Rostenkowski-Wolowitz. Aquarius: Sheldon Cooper. Pisces: Raj Koothrappali. That’s the character each Sun sign gets most often. Your Moon and the other planets can still change it.

Which Big Bang Theory character is a Leo?

Wil Wheaton first of all, then Penny. Leo guys usually get Wil Wheaton, Leo girls usually get Penny.

What science am I in The Big Bang Theory by birthday?

Your whole chart decides, not only the Sun. Still, some signs lean one way: Taurus, Virgo and Capricorn - Experimental physics; Aries, Leo and Sagittarius - The real world; Gemini, Aquarius and Pisces - Neuroscience & medicine; Aries and Capricorn - Microbiology.

Which Big Bang Theory character do people get most?

Bernadette Rostenkowski-Wolowitz. Out of random birthdays, that one comes up more than anyone else, most often for Capricorn, Aries and Virgo.

Which Big Bang Theory character is the rarest?

Mary Cooper and Beverly Hofstadter. They barely ever come up, so if NEBO gives you one of them, that’s a flex.

Does my birth time matter?

The date is enough. Add the time and city and your Ascendant joins in, which can move you to another character.
