Chemistry Through The Ages: How Humans Used Travel And Trade To Create Amazing Chemical Reactions
Humans have been discovering chemical processes since the Bronze Age, which is when our knowledge of chemistry really began to develop and expand.
During this time period, people discovered metals that were more durable and stronger than copper, such as bronze.
Making bronze was made possible through travel and trade–specifically by adding tin from Cornwall in southwest England to copper.
This combination proved much more reliable over time, thanks to its durability and strength, and it could even be found in bells and cymbals on drum kits.
Meanwhile, iron technology was being developed at the same time with charcoal and iron ore competing with bronze for popularity.
However, it lacked the same strength and resistance to corrosion that bronze possessed, so people resorted to iron due to its greater availability compared to other materials.
By forging advancements in smelting capabilities during this period of history all around the world–from India, sub-Saharan Africa, Mesopotamian regions–chemistry flourished as a human achievement during this time of profound discovery.
The Ancient World’S Secret Refining Techniques Led To Many Advances In Chemistry
Ancient humans have been refining materials and attempting to create gold since around 1200 BCE when Tapputi, a Babylonian woman, used myrrh and balsam to make her scented concoctions.
She also purified her recipes by heating them and collecting the vapors, which further confirms that this was an early reference to the process of distillation and filtration.
The Egyptians took it one step further in 550 BCE by using water to clear away debris and collect bits of gold.
King Croesus of Lydia then developed a technique for refinement, creating electrum — a gold-silver alloy — as a way to make pure gold.
Although the exact method for doing this is still being explored, research has shown that Lydians used molten lead and salt in their processes in order to give coins their own unique value — imprinting them with mythological figures, heroes or animals as symbols of exchange.
One type of material who might not need refinement is mercury — an extremely toxic liquid metal found in ancient Chinese tombs during Han dynasty times (c.
210 BCE).
Emperor Qin Shi Huang adopted large amounts of mercury into his own tomb by creating a replica of his palace set with miniature river made out of mercury itself!
Unfortunately, he even consumed small doses mercury-based medicines wrongly hoping that they could effectively grant him eternal life.
Ancients were able to take basic elements like water, mud or even mercurials and advanced their purification techniques in hopes for more precious metals such as gold so they are able leave behind wealth for generations after them or find cures for ailments like immortality.
The Search For The Philosopher’S Stone: Unveiling The Secrets Of Ancient Alchemy
The adage that some ancient techniques took hundreds of years to understand, while others remain a mystery, proves true when considering the invention of porcelain in around 200 AD.
The coveted ceramic was originally crafted with bone ash, glass, quartz, alabaster or feldspar and kaolin clay- a mixture only achievable with the right amounts of water and unprecedented levels of heat.
As production increased, forces outside China struggled to replicate the process and held tightly to their secrets.
It wasn’t until 1708 that alchemist Johan Frederick Botger and Ehrenfried Walther von Tschirnhaus cracked the code- only managing to do so when they acquired Kaolin Clay and Alabaster.
In 800 AD, Islamic and Chinese cultures were making amazing scientific advancements due to Abu Musa Jabir ibn Hayyan who practiced alchemy as well as numerology, astrology, and medicine.
Ivan’s hope for an elixir that could convert any metal into another was what he hoped for- something known as the philosopher’s stone; however, this hope never came to fruition due to a lack of decipherable symbols and mysterious language surrounding his work.
Good And Virtuous Intentions Can Lead To Unintended Consequences: The Case Of Gunpowder
It is often said that Good and virtuous intentions can sometimes lead to unintended consequences, and this can be seen throughout the history of chemistry and alchemy.
Take, for example, the attempts at transmuting metals into gold by Ibn Hayyan and other alchemists in China.
Though they were trying to achieve beautiful results, their efforts led to the development of gunpowder – an explosive product with far-reaching consequences.
The recipe for gunpowder started out with two main ingredients: sulfur and charcoal.
But it was not until the discovery of potassium nitrate – or saltpeter – that it became a true explosive.
After its effects spread across Asia through the Mongol empire, it eventually led to Europe’s creation of guns in 1326.
This completely changed warfare, leading to countless deaths in battles as well as unintended applications such as fireworks displays.
Another case where good intentions did not bring about desired results has been in attempts at creating life-extending elixirs.
Though progress was being made towards this goal by 1540 when Paracelsus recognized the effects outside agents might pose on human health, his discoveries ended up being instrumental in creating surgical anesthetics instead.
While we can learn from these stories that caution should be taken when experimenting or making decisions that could have unforeseen consequences, they also reveal how powerful our intentions can be once put into action!
The Arrival Of Quinine Signalled The Onset Of A New Era In Medicinal Chemistry Centred On Hard Science
The 17th century was a milestone in the history of medicinal chemistry – it marked the shift to hard science.
Before this period, alchemy dominated, but now new ideas and breakthroughs were calling for a change.
It all began with cinchona bark from South America, from which quinine was derived.
The Quechua people of Bolivia and Peru had already been using this in their medicine to treat symptoms like chills and shivering associated with malaria.
Jesuit missionaries soon spread news of the medical benefits of quinine back to Europe, where it quickly gained attention for its effectiveness against malaria.
In 1661, Robert Boyle published his work titled The Sceptical Chymist, which proposed a revolutionary way of understanding elements on an atomic level instead of relying on classical Greek assumptions of air, earth, fire and water.
His theories ended up being right – atoms really do form the basis components of all elements and reactions at an atomic level come together to explain what we observe around us every day.
Thanks to these developments by scientists like Robert Boyle, chemists have continued to make strides in advancing our knowledge about the world ever since.
This represents a major change from the prevalence of alchemical thinking during the previous century and proves that 17th century brought some groundbreaking discoveries that set off a chain reaction leading into modern science today!
The Historical Impact Of Chemical Synthesis: From Prussian Blue To Wohler’S Urea Synthesis
In the 18th and 19th centuries, chemical synthesis made huge leaps in advancement.
Thanks to figures like Johann Jacob Diesbach and Friedrich Wohler, scientists now had the ability to create new substances that had previously only occurred naturally in nature.
With Diesbach’s discovery of Prussian Blue, the door was opened for cheaper sources of blue oil paint to help eliminate the need to procure expensive lapis lazuli stones from Afghanistan.
On top of this, he also unlocked a whole new realm of chemistry possibilities by introducing hydrogen cyanide and a drug to treat metal poisoning.
Wohler’s efforts followed soon after with his successful synthesizing of urea using non-organic materials like mercury cyanate.
This sparked a debate around vitalism that still lingers in modern times, challenging us all to think about what it truly means for something to be alive.
Schönbein’S Contributions To Chemistry Show How Many Landmark Discoveries Take More Than One Person
We can see this illustrated through Christian Friedrich Schönbein’s contributions to the field of chemistry.
His own discovery of nitrocellulose -better known as guncotton- was built upon a decades later by Italian chemist Ascanio Sobrero, who explored what happened when he nitrated glycerine.
Sobrero had created something even more powerful than Schönbein’s guncotton: nitroglycerine.
This substance would take yet another contribution by Alfred Nobel to stabilize it in order to make what we now know as dynamite.
Schönbein also discovered ozone in 1840 when experimenting with electric currents and water, noticing a distinct odor.
This is not just true for Schönbein -aborning discoveries need to build on each other in order to unlock maximum potential and give us revolutionary products or advances in technology.
Indeed, multiple discoveries are sometimes needed for a landmark event!
The Message Is Clear: Toxic Substances Can Be Dangerous But Also Extremely Useful
Throughout history, various substances have posed a risk to public health and safety in one way or another.
We’ve seen this with mirrors, for instance.
Back in the day, mirrors were made with tin foil and liquid mercury – a corrosivemetal that’s potentially poisonous.
However, in 1856, German chemist Justus von Liebig formulated a safer, more effective process.
His method involved creating a silver/amine complex and combining it with sugar so it could be oxidized by the silver and reduced to an extremely reflective layer of elemental silver.
Unfortunately though, if this solution isn’t used right away, it can undergo chemical reactions that produce silver nitride- an incredibly unstable substance which can suddenly explode with no apparent cause!
Diazomethane is another problematic compound that requires special glassware and immense care when being handled as its volatile nature makes it prone to exploding upon exposure to sunlight, heat or sharp edges.
Despite these risks though, diazomethane still works great as a reagent – capable of helping chemists get all sorts of reactions going quickly and efficiently.
Lastly we come to cyanide – something that’s almost synonymous with poison.
It has long been used in the extraction and purification of gold because of how cost effective it is – leading some places to enact bans on its usage due to their large amounts of cyanide-infused water produced during the process.
The Danger Of Not Knowing The Real Effects Of Radioactivity: A Look At Eben Byers’ Tragic Fate
The Chemistry Book is an incredibly informative book that sheds light on some of the biggest developments in the early twentieth century, one of which being our understanding of radioactive substances.
But it also shows us some of the big dangers associated with these discoveries, and perhaps none so starkly as what happened to Marie and Pierre Curie.
The couple worked hard at isolating polonium and radium, even sacrificing their own health along the way.
Even though they had no idea about the dangers of radiation at this time, simply handling pitchblende for hours a day day exposed them to high levels of radiation.
In fact, even today their lab books are still too dangerous to handle without appropriate protective clothing!
Eben Byers’ story is no less tragic: he was a victim to drinking high doses of ‘Radithor’, a tonic that contained radium yet was never tested before entering the market.
This ultimately led to his death due to bone cancer-and his final resting place inside a lead lined coffin.
Thankfully, his story helped kickstart stronger federal regulations on products with radioactive components.
This serves as a reminder that while discoveries can open many doors, they sometimes come at a heavy cost.
The Danger Of Ignoring Scientific Warning Signs: The Story Of Tetraethyl Lead And Freon
It wasn’t until 1965 that the full extent of lead contamination caused by the use of tetraethyl lead in automotive gasoline was understood.
The development of this chemical additive to fuel had been spearheaded by General Motors head Charles Kettering and chemist Thomas Midgley Jr., who swore at a press conference that tetraethyl lead was safe, despite many deaths having occurred during its manufacture.
Clair Cameron Patterson’s tireless research would eventually reveal how wrong Midgley had been – his book Contaminated and Natural Lead Environments of Man detailed the dramatic increase in global lead levels brought about by petroleum-based products such as cars and planes.
The public became aware of the devastating repercussions to public health and environment, and slowly, countries began to ban lead from all products, although not before many lives had been impacted by this toxic substance.
It took almost half a century (until 1965) for us to understand the true scale of this problem – an all too important lesson in hindsight!
The Dangers Of Chemical Carelessness: A Lesson From Bhopal
The twentieth century was full of disasters caused by chemical developments.
Before the invention of Freon, many refrigerators used to work with propane, ammonia and sulfur dioxide – all of which were dangerous in their own right.
While Freon provided some relief, it was discovered many years later that chlorine free radicals were being released into the atmosphere because of this gas.
If not stopped, this would result in permanent damage to the ozone layer and put people’s health at risk.
It turned out to be even worse than imagined when Bhopal, India experienced a chemical disaster in 1984 due to the use of a compound called methyl isocyanate (MIC).
Half a million residents witnessed MIC entering the atmosphere which could cause eye irritation and serious lung trauma if levels surpassed more than 20 parts per million!
The twentieth century serves as an important reminder for us today about the effect chemicals have on our environment and well-being if substances aren’t handled with caution or care.
Modern Research Techniques In Chemistry And Biology Lead To Life-Saving Drugs
Modern research techniques have revolutionized the development of life-saving drugs, such as those used to fight malaria, cancer, bacterial infections and HIV/AIDS.
Two revolutionary American scientists at the forefront of this modern effort in drug development are Gertrude Belle Elion and George Herbert Hitchings, who were awarded the 1988 Nobel Prize for their groundbreaking contribution.
The duo pioneered the use of purine derivatives, which helped form DNA biomolecules needed for new drug treatments.
Similarly, Scottish physician Sir James Whyte Black has had an important impact on the world of pharmaceuticals with two of his notable drugs being cimetidine and propranolol — both highly successful treatments.
More recently, Merck and Codexis successfully engineered enzymes to enable more efficient syntheses like that of sitagliptin — another popular diabetes medication.
While this process is still costly and slow it is a first step towards making enzyme engineering common in drug development.
These advances in science have opened up an exciting array of opportunities for medicine that weren’t possible before — literally saving lives!
The Future Of Chemistry Looks Bright With Innovations To Reduce Carbon Dioxide Emissions In The Works
The future of chemistry could bring us important milestones which involve the reduction of carbon dioxide emissions.
Currently, many of our energy sources add to the greenhouse effect and raise the level of CO2 in our atmosphere.
But, if we’re smart about it, we can look for cleaner and more sustainable fuel sources such as hydrogen.
Hydrogen has been seen as a possible answer since at least the 1970s, but scientists need to solve one major problem – it’s very difficult to store.
However, advancements in technology may enable us to store this fuel safely by 2025 and make use of a clean energy source with fewer emissions.
Another area that scientists should continue to develop is artificial photosynthesis, which could be available around 2030.
This involves copying a plant enzyme – Rubisco – which turns carbon dioxide into glucose during photosynthesis and produces oxygen in the process.
The only issue is that Rubisco is extremely slow (only three molecular changes per second) so chemists are looking for ways to speed up this process or even bypass it entirely so they can cut down on CO2 emissions.
These therapies have the potential to save our planet from climate change, yet still there’s much work left to do from today’s chemists if these goals are going to be achieved.
