10 Scientists who Were Killed by Their Own Experiments

10 Scientists who Were Killed by Their Own Experiments

These are the great people whose discoveries have changed the world but they were unfortunate as they died or injured themselves while performing their experiments. The advances they have made to science are incredible and many of them opened the doors for some of man’s greatest discoveries and inventions.

1. David Brewster


 Sir David was a Scottish scientist, and a writer. Optics and light polarization was the field of his interest. Optics is a a field requiring excellent vision. In 1831, Sir David performed a chemical experiment which almost blinded him. He remained affected with eye troubles until his death. Sir David Brewster is well known as the inventor of the kaleidoscope – a toy that has gives joy to millions of children over the years.


2. Alexander Bogdanov


 Alexander Bogdanov was a Russian physician, philosopher, economist, and a science fiction writer. In 1924, he started experiments with blood transfusion. After performing 11 transfusions himself, he stated that he had suspended his balding, and improved his eyesight. Unfortunately, Bogdanov forgot to test the health of the blood of the donor which he was using. In 1928, Bogdanov took a transfusion of blood infected with malaria and tuberculosis which made him died shortly.


3. Karl Scheele


Scheele was a pharmaceutical chemist and had discovered many chemical elements. The most notable of his discoveries were oxygen, molybdenum, tungsten, manganese and chlorine. He also discovered a process very similar to pasteurization. Scheele had the habit of taste testing his discoveries and managed to survive his taste-test of hydrogen cyanide. But he was unfortunate while tasting mercury and died from the symptoms of mercury poisoning.

4. Elizabeth Ascheim


After the death of the mother, Elizabeth Fleischman Ascheim married her family doctor, Woolf. Woolf was very much exited about the new discovery of Wilhelm Conrad Röntgen x-rays. His wife also became equally interested in it and she gave up her job as a bookkeeper to continue studies in electrical science. Finally, she bought an x-ray machine and kept it in her husbands office which was the first x-ray lab in San Francisco.
Using themselves as subjects, She and her husband spent some years in experimenting with the machine. Unfortunately, they did not realize the consequences of their lack of protection to x-rays and Elizabeth died of an extremely widespread and violent cancer.


5. Jean Francois De Rozier


Jean Francois was a teacher of chemistry and physics. In 1783, he witnessed the world’s first balloon flight that created a passion in him for flight. After testing various flights of a sheep, a chicken, and a duck, he took the first manned free flight in a balloon. He traveled at an altitude of 3,000 feet using a hot air balloon. Later, De Rozier planned a crossing of the English Channel from France to England. He took the flight but unfortunately after reaching 1,500 feet in a combined hot air and gas balloon, the balloon deflated and made him to fall to his death.

 6. Humphry Davy

 Humphry Davy was a brilliant British chemist and inventor. He got a very rough start to his science career. As a young trainee, he was fired from his job because he caused too many explosions while performing experiments. He was so much passionate about chemistry that he took it up as the field of his career. He had a habit of inhaling various gases while dealing with them. Luckily this habit led to his discovery of the anesthetic properties of nitrous oxide. But, unfortunately, this same habit led to him nearly killing himself on many occasions. The frequent poisonings of gases made him useless for the remaining two decades of his life. He had also damaged his eyes permanently in a nitrogen trichloride explosion.


7. Michael Faraday


 After the injury of a brilliant British chemist Sir Humphrey Davy’s eyes, Faraday became an trainee to him. He made efforts to improve Davy’s methods of electrolysis and to make useful discoveries in the field of electro-magnetics. Unfortunately, Faraday also suffered damage to his eyes in a nitrogen chloride explosion. He spent the rest of his life suffering with chronic chemical poisoning.


8. Galileo Galilei


Galileo also referred to as the “father of modern physics”.  His work on the refinement of the telescope was brilliant. It opened up the doors of the universe for future generations. But it also damaged his eyesight. He was fascinated with the sun and spent many hours staring at it. As a result of which, he got extreme damage to his retinas. This was the most likely cause of his near blindness in the last four years of his life.

9. Louis Slotin


Slotin worked on the US project to design the first nuclear bomb. While performing experiments for his project, he accidentally dropped a sphere of beryllium on a second sphere causing a prompt critical. It is known from other scientists who were in the room that they had witnessed a blue glow of air ionization and felt a heat wave. Slotin was rushed to hospital where he died nine days later.

The amount of radiation he was exposed to was equivalent to standing 4800 feet away from an atomic bomb explosion.

10. Marie Curie


 Curie along with her husband Pierre discovered radium in 1898. She spent rest of her life performing radiation research and studying radiation therapy. Her constant exposure to radiation led to her contracting leukemia and due to which she died in 1934. Curie is the first and only person who received two Nobel prizes in science in two different fields, chemistry and physics.

Facts about Bill Gates and His House

One of the most interesting things you’d experience if you lived in this house is that you wear a pin containing a microchip which acts as your ID.  When you walk into a room, Lighting , sound, and temp controls are customized for you. Any high resolution display that you walk by will know that you’re there, and your favorite art is displayed. And if you’re getting a phone call, only the phone nearest to you will ring. This is all thanks to the pin with the microchip.

 

Random Facts

  • The house is 50,000 square feet
  • In 2005, the house and land were assessed at $200 million
  • Annually, Gates pays nearly $1 million dollars in taxes for the property
  • Over 64 km of optical fiber was used in the house
  • 300 workers at one time were working on the house – 104 of them were electricians
  • Every door handle in the house was custom made and cost $2,000 each
  • There are no visible electric outlets in the house


His full Name Sir. Dr. “William Henry Gates III”
1. Bill Gates earn U.S. $ 250 every SECOND, that’s about U.S. $ 20 million a day and U.S. $ 7.8 billion a year.
2. If he dropped to U.S. $ 1,000, he did not even bother anymore to get it back because of time equal to 4 seconds to take, he had earned the same amount.
3. U.S. national debt of about U.S. $ 5.62 trillion, if Bill Gates will pay the debt by himself, he would pay it off in less than 10 years.
4. He can donate U.S. $ 15 to everyone in the world but still can save U.S. $ 5 million for his pocket money.
5. Michael Jordan is the athletes who paid the most expensive in America. If he does not eat and drink and still leave intact a year income of U.S. $ 30 million, he still had to wait until 277 years to become as rich as Bill Gates now.
6. If Bill Gates were a country, he will become the world’s richest country to number 37 or if He is himself is company, He will be largest American company number 13, even larger than IBM.
7. If all the money Bill Gates exchangeable into pieces U.S. $ 1, we can arrange a road from earth to the moon, 14 times back and forth. But the way it should be made non-stop for 1,400 years and used a total of 713 Boeing 747 planes to transport all the money.
8. Count from He was 40 years old. If we assume that he can live 35 years longer then he has to spend U.S. $ 6.78 million per day to spend all his money before he went to heaven.
9. But! If Microsoft Windows’ users can claim U.S. $ 1 for every time their computers hang because of Microsoft Windows, Bill Gates will be bankrupt in 3 years!

Design a creative modern menu – Photoshop Tutorial

In today’s tutorial we’re going to teach you how to make a modern, sleek and creative navigation menu.
There’s a lot of things going on in here. You will learn how to add depth into text and other small shapes, create a 3D shape the easy way and apply gradients to get a realistic lightning.
The techniques learned throughout this tutorial can be applied in many more ways and are definitely worth learning.
So let’s get started right away.

Result Preview:



Step1

Create a new file of 1000px wide and 400px wide

Step2

Select the ellipse tool

And draw a flat ellipse like so:


If you’re unsure about what size you’re going with, try making it about 22.5 wide and 3.7 high. You can see this by opening the Info menu located under Window>Info or by pressing F8

Step3

Double click this layer with the shape in order to get the Layer Style window.
Add a Drop Shadow:
Blend mode: Normal
Color: White
Opacity 75%
Angle 90° – Deselect “Use Global Light”
Distance: 0px
Spread: 0px
Size: 5px

Add an Inner Shadow:
Blend mode: multiply
Color: black
Opacity: 100%
Angle: 90° – Deselect “Use Global Light”
Distance: 0px
Spread: 0px
Size 61px

And finally add an Inner glow:
Blend mode: normal
Opacity: 75%
Noise: 0%
Color: White
Choke: 9%
Size: 90px

Step4

To prevent ourselves from any clutter, we’re going to rename the layer we just edited. Double click on the name and rename it to “Top”.

Step5

Make sure the layer is selected and press ctrl+J (Windows) or cmd+J if you’re on a Mac.
This will duplicate the layer, now make sure the new layer is selected and press V to access the resize tool.
Hold Alt+Shift and drag one of the corners until you get something like this:

You might want to make the height a little bit smaller by holding Alt and dragging the upper or lower nod up or down, just a few pixels.

Step6

Rename this new layer to “Dark Center”

Step7

Double click the Dark Center layer and add the following styles:
Drop Shadow:
Blend mode: Normal
Color: white
Opacity: 75%
Angle: 90° – Deselect “Use Global Light”
Distance: 1px
Spread: 0%
Size: 2px
Inner Shadow:
Blend Mode: Multiply
Color: Black
Opacity: 75%
Angle: 90% – deselect “Use Global Light”
Distance: 1px
Choke: 0%
Size: 2px
Gradient Overlay:
Select “Reverse”
Style: Reflected
Angle 96°
Color: from #3d3d3d to #5b5b5a

Step8

Now we’re going to create the bottom part of the navigation, you could do it with the pen tool, that’s the hard way. But let’s just duplicate the Top layer so often that it becomes the same shape.
So select the Top layer, hold Alt and press the down arrow about 25 to 30 times. (I prefer 26)
Select all these layers that you just produced by clicking the one at the top, scrolling down in the layer menu and hold down shift and then click the first copied one (NOT the original). Then press ctrl+E to merge all those newly created layers.
Now you should have 2 layers, drag the “Top” layer above the copied one.

Step9

Now for our own ease, we need to remove the part we don’t see.
To make things less confusing, name the new layer to “Nav Bar”.
Then click Ctrl+click (cmd+click on Mac) the grey image of the “Top” shape layer.
It looks like this:

The ellipse will be selected, now go to the “Nav Bar” layer and hit Delete or Backspace to erase that area on just this layer. You can double check if it worked by hidding the “Top” layer (just click the little eye icon next to it).

Step10

On the “Nav Bar” layer we’re going to add a layer style.
Gradient Overlay:
Color: From #414141 (at Location 0%) to
#737474 (at Location 15%) to
#adadad (at Location 50%) to
#737474 (at Location 85%) to
#414141 (at Location 0%) to

Step11

Now duplicate the “Top” layer once again, but just 1 time by pressing Ctrl(or cmd for Mac)+J.
Move this layer all the way down, just above your background layer.
Move it down by pressing V for the right tool and then holding Shift and pressing the down arrow 8 to 9 times (I prefer 8).

Step12

Remove all the Layer Styles of the copied layer and only add a Color Overlay that’s totally black.

Rename the layer to “Shadow”.

Step13

Make sure your Shadow layer is still selected and go to the Filter menu>Blur>Motion Blur.

A window will pop up asking you if you want to rasterize the layer, press OK.
A new window with the settings will come up, change the Distance to 123 pixels.

You should have something close to this now:

As you might have noticed, the shadow is till a bit hard, especially at the bottom.
We start making it better by turning the Opacity of the Shadow layer to 75%

Step14

Pick the Blur Tool

and use the following Brush Settings (right click):

Make sure the “Shadow” layer is still selected and wipe over the bottom area about 5 times up to 10. The edge should look slightly softer now.

Step15

Create a new layer above all the other ones and select the Text Tool (T)
Type in the name you want and place it in the center of the black ellipse.
Avoid lowercase typing, because letters like g p and so on will break the effect.

Step16

We’re going to add a few layer styles to the text.
Gradient Overlay:
Angle: 90°
Color: From #afb0ad to #e2e4dd

Stroke:
Size: 1px
Opacity: 82%
Color: White
It should look something like this:

Step17

Select the text layer, duplicate it by pressing Ctrl+J (or cmd+J) and drag the new layer below the original one.
Remove all the effects and make sure the text is black.

Step18

Move the text down 1 time with Shift+Down Arrow.
Add Filters>Blur>Gaussian Blur with 4pixels radius.

Make the layer’s opacity 75% for a smoother look.

Step19

Nobs will show up and you can now position the rectangle to the center. Now hold Alt and drag at the left or right nob to get a selection about twice as big as we just started with.
Hit Enter and make sure the “Selection” layer is selected. Now press Ctrl+Shift+I to invert the selection and press Delete or Backspace to remove it.
It will look weird and confusing for a second, but just go on and let’s restyle the layer:
Gradient Overlay:
From #87c540 to #c9da2b

Apply Stroke
Stroke: 1px
Opacity: 16%
Color: Black

Step20

Create a new layer above the “Selection” layer.
Pick the Rectangle Tool (U)

And draw a tiny rectangle like this:

Step21

Now let’s add some Layers Styles again:
Drop Shadow:
Blend mode: Multiply
Color: Black
Opacity: 55%
Angle: 90° – deselect “Use Global Light”
Distance: 0px
Spread: 0%
Size: 5px
Gradient Overlay:
From #2f2f2f to #868686

Step22

Create a new layer on top of the rectangle one and pick the Text tool.
Search a bit what font size you need, many fonts require a different size to fit the “Selection” box.
To this text we’ll add some effects once again.
Drop Shadow:
Blend mode: Normal
Color: White
Opacity: 75%
Angle: 90° – deselect “Use Global Light”
Distance: 1px
Spread 0%
Size: 1px
Color Overlay:
Color: Black
Now the finishing touches.
That is it!
