Tyge Ottesen Brahe "Tycho"
(Tee-ko Brah)
Danish astronomer and alchemist, 1546–1601

"the greatest pre-telescope Astronomer"
....astrologer, astronomer, alchemist
magi...occultist....alchemical and herbal medicine creator/pharmacist
.... or what can happen if we fully fund science
Early Life
-
smelted a brass prosthetic nose & attached w/ paste. May have had silver/gold ones for formal occasions.
-
once had ~1% of Denmark's wealth

“The combination of two hot-blooded young men, heavy drinking and the universal carriage of swords made violence inevitable.”


- noble, kidnapped by uncle at age 2 ....but parents didn't mind
- uncle died after saving King Frederick II from drowning
- witnessed a solar eclipse, left law for science ....particularly impressed that such an event could be predicted
-
duel at age 20
-
in the middle of the night
-
with his 3rd cousin
-
because of an argument
-
at an engagement party
-
about a math problem
-
-
lost the bridge of his nose & got scar on forehead


Tycho's supernova (remnant)

Observed 1572 type 1a supernova
-
showed it wasn't in the atmosphere
-
had to be further than the moon
-
contradicted Aristotle and undermined christianity, universe not 'unchanging'
-
later inspiration for Edgar Allan Poe's poem "Al Aaraaf"
Fame
Great Comet of 1577
showed must be beyond the moon → no celestial spheres


preface to De nova stella: "O crassa ingenia. O caecos coeli spectatores"
("O thick wits. O blind watchers of the sky")
Innovations:
-
defined astronomy from astrology, and tied physics & astronomy
-
pioneer in astrometry before telescopes
-
particularly in instrumentation
-
30 yrs of naked eye data

- order of magnitude better than anything prior
- 30 arcsecs (1/60th size of moon)
- observed 1,000 stars ...made a catalog

Uraniborg, the first modern research institute?
- given Hven island, built Uraniborg observatory...the best in the world, first time surpassing the Islamic observatories.
- open correspondence b/t scientists
- shared instruments and designs
- not for intellectual property or profit, but for honor.
-
alchemical lab in basement
-
employed 100 people
-
built their own printing press to publish
-
pressurized water system & flushing toilets
-
on scale of museum of Alexandria, 2000 yrs prior
-
ultimately the 8 km² island was worth 5% the GNP of Denmark


Uraniborg
on Hven island
Stjerneborg

-
made a couple dozen new astronomical instruments
- Quarans Muralis (giant quadrant/mural)
- Globus Magnus (5ft celestial sphere, lost in the 30 yrs war)...on which he plotted his observations
-
observations critical for science
-
test rather than just accepting what was published
-
standard celestial coordinates (not based on zodiac)
-
RA and Dec, by use of quadrant and a clock
-
-
intermediate model of solar system, hydrid of geo- and helio-centric
-
universe has physical nature and Earth is tiny compared to other astronomical bodies

- increased the size of his instruments
- used metal and masonry rather than wood
- instruments were built in crypts
- permanently and solidly mounted;
- carefully analyzed all the errors

- never married, cohabitated w/ a peasant woman named Kirstine (scandalous)
- Jepp.....the 'clarivoyant' dwarf he employed, stayed under the table during dinner (literally)
- tame pet moose (elk?), lent out for parties....
- would trot alongside Brahe's carriage like a loyal dog and lived inside his castle
- supposedly Tycho and the elk once got into a drinking contest and Tycho won......



“the moose had ascended the castle stairs and drunk of the beer in such amounts that it had fallen down [them]” to its eventual demise.

a few ....let's call them quirks:
In 1600 Tycho took Kepler as an assistant....
- though he never trusted him:
- low status
- 25 yrs younger
- mother accused of witchcraft
- father a mercenary
- bad eyes and hands from smallpox as a child
- mathematician/theologian
- nested platonic / harmonic design obsession
- Copernican heliocentric model believer, 6 nested spheres, with Sun at center....wrong in all the reasoning and logic but at least right about the model.....but lacked data
- Tycho observed planet positions against stars for 20 yrs (data Kepler wanted)

Tycho and Kepler were opposites: Empiricist vs Rationalist, rich vs poor, indulgent vs pious



from Mysterium Cosmographicum (1596)
- Kepler
- Tycho's cousin, Erik
- on behalf of the son of king Christian IV of Denmark (for sleeping with the queen)
- poisoned himself through alchemy ...or from his prosthetic nose
- exhumed, twice: 1901 and 2010
- tested for mercury poisoning
- traces found in his mustache but not enough to kill him
- probable death by enlarged prostate/infection, died 11 days after party, age 54
- was likely diabetic, obese, and alcoholic.


death.... and possible murder?
According to Kepler, Tycho had refused to leave the banquet to relieve himself because it would have been a breach of etiquette
"He lived like a sage and died like a fool."
-Tycho



Kepler made off with the data.... made his 3 laws of planetary motion
Hven Island

Tycho's relatives
Something rotten in Denmark?
- Hamlet, written in 1601, the same year as Tycho's death
- Shakespeare undoubtedly knew of Tycho's discovery
- refers to "uncle father" and "mother-aunt" ....Tycho did have these....
- refers to "a bright star westward from the pole"
- Uraniborg observatory is 9 miles from Elsinore (setting of Hamlet)
