🎓 Early Life and Education of Wilhelm Conrad Röntgen

Wilhelm Conrad Röntgen, a renowned physicist and Nobel laureate, was born on March 27, 1845, in Lennep, Germany. He was the only child of a cloth merchant and moved to the Netherlands at a young age. His formal education was disrupted at 18 when he was expelled from school due to a false accusation. Despite this setback, Röntgen continued his education informally at the University of Utrecht and later at the Federal Polytechnic Institute in Zurich, where he was allowed to study without a high school diploma. At 23, he graduated with a degree in mechanical engineering, and a year later, he earned his doctorate for his research on gas volumes and temperatures. Röntgen's early career was marked by a series of academic positions, including a stint as an unpaid assistant in Würzburg and a lecturer in Strasbourg. He eventually achieved his habilitation and settled in Geesen in 1879, where he confirmed James Clerk Maxwell's theory of displacement current, earning him global recognition.

🔬 The Discovery of X-Rays and Its Impact

In 1895, while working with cathode ray tubes, Röntgen discovered a new form of radiation that he termed 'X-rays'. He observed that these rays could penetrate various materials, including the human body, which he demonstrated with the first documented X-ray image of his wife's hand. Röntgen's discovery was a pivotal moment in science, and he quickly shared his findings with the scientific community. His work led to him being awarded the first Nobel Prize in Physics in 1901. Despite the accolades, Röntgen remained humble and did not patent his method for generating X-rays, wanting the benefits to be accessible to all. He also declined a noble title offered by the Prince Regent of Bavaria. Röntgen's discovery has had a profound impact on the world, leading to numerous applications in medicine and technology that continue to shape our daily lives.

this progress comes at a high cost

play03:57

people work an average of 70 hours per

week

play04:00

and rooms frequently have up to five or

from this phenomenon hunken concludes

that there must be an

play05:02

unknown kind of radiation which he calls

play05:05

x-rays one of the finest hours of

science but what happened

play05:12

in those vacuum tubes electrons are

accelerated from cathode to anode

play05:17

by a high voltage

play05:20

during their passage they excite gas

play05:22

molecules in the tube to give light

play05:26

but when reaching the anode the fast

play05:28

electrons are suddenly decelerated

play05:31

and deflected forcing them to release

wilhelm konrad runkan immediately

he sends special prints of his article

newspapers from berlin

play06:24

vienna and around the globe report on

his groundbreaking discovery

play06:30

the emerging interest in his person

play06:32

makes gruntken feel increasingly

play06:34

uncomfortable

play06:36

in the beginning of 1896 he holds his

first and

play06:40

only oral presentation of the new

radiation

play06:43

afterwards the anatomist professor

play06:46

albert colica

play06:47

who is present as one of the listeners

play06:49

suggests to call the x-rays runtgen

play06:52

radiation

play06:54

the audience applauds this proposal with

play06:56

standing ovations

play06:59

in private life however grunken is

play07:01

indeed a social type

play07:03

whenever work allows he leaves his lab

play07:05

in order to go on vacation with friends

play07:07

for hiking or hunting luxury

play07:10

in contrast is not for him he hesitates

play07:13

to enter expensive hotels

play07:15

and will only do it for the sake of his

play07:17

wife whose health

play07:18

is not at its best also

play07:22

as a professional huntkin is humble he

play07:24

does not apply for a patent for the

play07:26

generation of x-ray radiation

play07:28

he wants everybody to benefit from his

play07:30

discovery

play07:32

some react with mockery and in

play07:34

comprehension such as the inventor and

play07:36

businessman

play07:37

thomas edison likewise

play07:41

grunken isn't flattered by honors and

play07:43

medals

play07:44

culminating in the denial of being

play07:46

ennobled by the prince regent lloyd port

play07:49

which evokes astonishment and also

play07:51

resentment at the ministry in munich

play07:56

however there is one honor that huncan

play07:58

appreciates

play07:59

and accepts in 1901 he is awarded the

play08:03

first

play08:03

nobel prize in physics the ceremony

play08:07

requires a trip to stockholm

play08:08

hundken is rather unexcited in his

play08:11

request to leave

play08:12

he writes since these prizes have an

play08:15

exceptionally high value

play08:17

and are very honorable the differential

play08:21

obedience honey believes

play08:22

though somewhat wary that he has to

play08:25

adhere to the wishes of the royal

play08:27

swedish academy

play08:29

therefore requesting vacation for the

play08:31

duration of the coming week

play08:34

on the day after the award ceremony

play08:36

huntkin already makes his trip back

play08:38

without giving the customary ceremonial

play08:41

address

play08:43

today we don't know what was behind his

play08:45

apparent shyness

play08:47

rundeck had had most of his

play08:48

documentation destroyed after he died

play08:51

so many things remain unknown or

play08:53

mysterious

play08:54

for example it's still unclear why he

play08:57

soon stopped committing himself to a

play08:59

closer investigation of x-ray radiation

play09:03

in any case wilhelm conrad rankin's

play09:05

discovery

play09:06

changed the world to this day
