Little Animals in the Rain

0:00 / 3:34

Lyrics

Delft was a Dutch town of bridges and bricks,

The year was sixteen seventy-six,

There Antonie van Leeuwenhoek sold cloth,

But tiny things were hidden out of sight,

So he shaped tiny lenses, round and bright,

He set each lens inside a metal plate,

He held them up to the window light,

Then he caught some rain from the roof one day.

His microscope was a lens in brass,

It worked like a magnifying glass,

It made the tiny things look big,

And Leeuwenhoek looked and looked again,

He saw what we now call microbes,

Little Animals in the Rain.

He caught more rain and watched it day by day,

At first, he only saw a few, so small,

Then a thousand swam in a single drop,

A grain of sand was bigger than them all,

He sealed a letter and sent it out,

In London, scientists started to doubt,

Back home, he asked witnesses to look through,

They saw the little animals swim too.

His microscope was a lens in brass,

It worked like a magnifying glass,

It made the tiny things look big,

And Leeuwenhoek looked and looked again,

He saw what we now call microbes,

Little Animals in the Rain.

In London, scientist Robert Hooke tried,

But at first, the drops looked empty inside,

So he followed Leeuwenhoek's recipe,

And at last, Hooke saw them, plain to see.

Today, you use a microscope in class,

You drip some puddle water on the glass,

You turn the knob until the drop looks clear,

And swimming microbes suddenly appear.

His microscope was a lens in brass,

It worked like a magnifying glass,

It made the tiny things look big,

And Leeuwenhoek looked and looked again,

Now you can see the microbes too,

Little Animals in the Rain.

Through Leeuwenhoek's microscope, they looked big.

The problem
Nobody had ever seen a living thing too small for the eye. A drop of rain looked like nothing at all.
The idea
A cloth merchant ground a tiny bead of glass, set it in a little brass plate and held it close to his eye. One lens, no tube, but it made a raindrop's world look hundreds of times bigger.

Microscopes are how a hospital lab finds the germ behind an infection and picks the medicine that will beat it.
Did you know?
His letter of 9 October 1676 to the Royal Society in London described 'little animals' swimming in rain water: the first written account of bacteria. Robert Hooke, the Society's Curator of Experiments, saw them for himself in November 1677.

Learn · try itHow digitalis from the foxglove works
The problem
Dropsy, the swelling that comes when a weak heart cannot keep the blood moving, had no medicine that reliably helped.
The idea
A family remedy of twenty or more herbs worked when doctors' medicines failed. Withering worked out that the foxglove leaf was the active part, dried and powdered it, and found by careful trial how small a dose helps without poisoning.
Today
Digoxin, a medicine from the foxglove family, is still prescribed to help some failing or irregular hearts, always in tiny measured doses.
Did you know?
In 1775 Withering was asked about a dropsy remedy long kept secret by an old woman in Shropshire. After about ten years of trials he published An Account of the Foxglove in 1785, reporting every case in which he had used it, good or bad.

The ophthalmoscope · Ophthalmology
Watch the film: Look Into My Eyes
Learn · try itHow the ophthalmoscope works
The problem
Doctors had no way to see inside a living human eye to examine the retina.
The idea
Helmholtz built a simple hand mirror of tilted glass plates that reflected candlelight into the eye and let the examiner look along the same line of sight into the retina - the first working ophthalmoscope.
Today
The ophthalmoscope, refined into modern versions, remains a standard tool in every eye exam worldwide.
Did you know?
On 6 December 1850 Hermann von Helmholtz, then a 29-year-old professor of physiology at Koenigsberg, demonstrated his ophthalmoscope to the Berlin Physical Society, and published a full description in 1851. The eye surgeon Albrecht von Graefe became its first routine clinical user and said Helmholtz had ‘opened a new world’ to ophthalmology; in 1858 Graefe presented him with a cup inscribed to ‘the creator of a new science.’

The problem
A doctor could not see a broken bone or a swallowed coin without cutting the skin open to look.
The idea
A glass tube fired by a high-voltage spark sends out invisible rays. They pass through skin and flesh like light through fog, but bone and metal block them, so the bones leave a shadow on a glowing screen or a photographic plate.
Today
X-rays show the doctor where an arm is broken, and the dentist checks your teeth with one in a second.
Did you know?
On the evening of 8 November 1895 a coated paper screen two metres from Röntgen's covered tube began to glow. On 22 December he photographed his wife Anna Bertha's hand, its bones and her ring showing through. He took no patent on the rays, and in 1901 he won the first Nobel Prize in Physics.

The ABO blood groups · Hematology / Transfusion medicine
Watch the film: Not a Vampire
Learn · try itHow the ABO blood groups works
The problem
Early blood transfusions between people sometimes worked and sometimes killed the patient, and no one knew why.
The idea
Landsteiner mixed red blood cells and serum from himself and his laboratory colleagues on glass slides. Some mixtures stayed smooth; others clumped. He sorted the pattern into blood groups A, B and O (AB was identified the following year by colleagues), explaining why some transfusions were compatible and others were not.
Today
Blood typing before every transfusion, standard practice worldwide, traces directly back to Landsteiner's 1900 bench experiment.
Did you know?
Landsteiner published his findings in 1900-1901 while working in Vienna. In 1907, Reuben Ottenberg in New York was the first to use blood-group matching (crossmatching) before a transfusion in clinical practice, performing 125 successful transfusions with no bad reactions. Landsteiner received the Nobel Prize in Physiology or Medicine in 1930 for the discovery.

The Blood Bank
Bernard Fantus (1874–1940)
The hospital blood bank · Transfusion medicine
Watch the film: The Blood Bank
Learn · try itHow the hospital blood bank works
The problem
A patient who needed blood in an emergency had to wait for a matching donor to be found and brought to the hospital on the spot.
The idea
Fantus, director of pharmacology and therapeutics at Cook County Hospital, kept donor blood in sealed, cooled glass bottles with sodium citrate added to stop it clotting, ready to use the moment it was needed. He coined the name ‘blood bank’ himself, likening it to a bank where the community made deposits of blood ‘on account’ for anyone who needed a withdrawal.
Today
Every hospital blood bank in the world today traces directly back to the one Fantus opened at Cook County Hospital.
Did you know?
The Cook County Hospital blood bank opened on 15 March 1937. Fantus described it in a landmark article in the Journal of the American Medical Association that July. In the year after it opened, transfusions at the hospital rose from 649 (in 1936) to 1,354.

Watch the film: Sausage Casings in Kampen
Learn · try itHow the rotating-drum artificial kidney works
The problem
When the kidneys stop working, waste builds up in the blood. In wartime Holland a patient with kidney failure had days to live.
The idea
Blood ran through long tubes of sausage casing wound round a wooden drum that turned in a bath. The casing let the small waste particles seep out into the bath and kept the blood cells in, so clean blood came back.
Try it · Turn the drum
Press Turn the drum: blood runs through the sausage-casing tube in its bath, the small waste bits slip out through the casing's pores and the blood cells stay in.
Clean blood

The blood is full of waste (the yellow dots). Turn the drum to wash it.
Today
Dialysis machines clean the blood of people whose kidneys have failed, often three times a week.

Medical ultrasound · Obstetric ultrasound
Watch the film: The Boilermaker's Echo
Learn · try itHow medical ultrasound works
The problem
A doctor could feel a swelling in a woman's belly but could not see inside it, so he often had to guess what it was until an operation showed him.
The idea
Boilermakers already checked steel for hidden cracks with sound too high to hear: a probe sends it in, and the echoes come back like a shout in a cave. Donald borrowed the idea, and Tom Brown built machines that turned the echoes into a picture.
Try it · Send a ping
Tap Send a ping: the probe clicks out sound too high to hear, and each boundary inside bounces an echo back. The later an echo returns, the deeper its dot goes. Ping across to draw the picture.
Peek inside
Nothing to see yet: inside the belly stays dark until echoes come back.
Today
A probe glides over a mother's belly and the whole family watches the baby move on the screen.
Did you know?
On 21 July 1955 Donald took specimens to the Babcock & Wilcox boiler works at Renfrew to test them with an industrial flaw detector. In 1958 he, John MacVicar and Tom Brown published their ultrasound pictures from inside the abdomen in The Lancet.

Learn · try itHow the Bird Mark 7 respirator works
The problem
When illness or injury stops someone breathing well enough on their own, every breath needs a push of air from outside.
The idea
A pilot who knew how air behaves under pressure built a small green box that pushes air gently into the lungs when a breath is due, then lets it flow back out: positive-pressure breathing.
Try it · Give a breath
Press and hold to try a breath: the machine adds a push of air and the lungs fill. Let go and they empty on their own.
Press and hold the button (or hold the space bar) to push a breath in.
Today
Ventilators breathe for patients in every intensive-care unit and ambulance.
Did you know?
Bird joined the Army Air Corps a week after Pearl Harbor and ferried bombers, fighters and transport planes. The Bird Mark 7 came out in 1958 in an opaque green case.

Watch the film: Four Little Lenses
Learn · try itHow the soft contact lens works
The problem
The contact lenses of the day were hard, and many people found them sore and dry after a few hours.
The idea
Spin a bowl of water and the water climbs its sides into a smooth curve. Spin a drop of liquid gel in a tiny cup and it sets in that same curve: a soft, clear lens.
Try it · Spin a lens
Drag the speed slider: the faster the little mould spins, the more its liquid gel climbs the sides and the deeper the surface curves. Find the speed that makes a thin, even curve, then let it set.
Spin speed
Not spinning: the liquid gel sits in a puddle at the bottom of the mould.
Today
Most people who wear contact lenses today wear soft ones.

The problem
Biologists had no way to see a living process happening inside a cell without killing or damaging it.
The idea
Shimomura and Frank Johnson hand-collected thousands of jellyfish at Friday Harbor and isolated a protein that glows green on its own. Decades later other scientists learned to attach it to other proteins like a tiny light, making living cells glow wherever that protein is at work.
Today
GFP and its relatives are standard lab tools worldwide, used to watch genes switch on, track cancer cells, and see nerve cells fire in a living brain.
Did you know?
In the summer of 1961 Osamu Shimomura and Frank Johnson hand-collected about 10,000 jellyfish (Aequorea victoria) at Friday Harbor Laboratories in Washington state and isolated the glowing protein from them. Shimomura shared the 2008 Nobel Prize in Chemistry with Martin Chalfie and Roger Y. Tsien for the discovery and development of GFP.

Learn · try itHow the clinical whole-body MRI scanner works
The problem
X-rays showed bones clearly, but soft organs and tumours inside the body often looked like grey shadows unless doctors operated.
The idea
Our bodies are mostly water. A giant four-ring magnet lines up the water's hydrogen nuclei like tiny compass needles, a pulse of radio waves tips them, and as they relax they send back faint radio signals that a computer turns into a clear picture, slice by slice, with no X-rays at all.
Try it · Listen to the water
Your body is mostly water. Switch the four-ring magnet on to line up the water's tiny compass needles, then send radio pulses: as they relax back into line, their signals build a slice of the chest.
Magnet off: the water's tiny compass needles inside the body point every which way, so they give no signal.
Today
MRI scanners in hospitals around the world image the brain, spine, heart, joints and soft tissues without ionising radiation.
Did you know?
On 28 August 1980 at Aberdeen Royal Infirmary, the Aberdeen team used their four-coil Mark-One scanner and spin-warp imaging to scan a patient from Fraserburgh, revealing tumours X-rays could not clearly show: the first clinically useful whole-body MRI scan of a hospital patient.

The problem
A baby born too early cannot keep itself warm, and far from a hospital incubator the cold can kill.
The idea
A tiny sleeping bag with a pouch of special wax: warm the pouch in hot water and, as the wax sets, it gives off heat and holds the baby at body temperature for hours, with no electricity.
Try it · Keep a baby warm
Drag through four hours. In an ordinary blanket a small baby cools below 36.5 °C; the warmed wax pouch gives off heat as its wax slowly sets and holds about 37 °C for hours.
