Period six- toilet

A toilet is a sanitation fixture used primarily for the disposal of human waste. They are often found in a small room referred to as a bathroom. Ancient civilizations used toilets attached to simple flowing water sewage systems included those of the Indus Valley Civilization and also those of the Romans and Egyptians. Although the first version of flush toilet system, which is widely used nowadays was designed in 1596 by John Harington, such systems did not come into widespread use until the late nineteenth century.

Toilet began with a simple flushing system and eventually transformed into multi-purpose bidet toilet. This evolution is an evidence of the technological advancement and rising living standard of human. Effective sanitation system led to the decrease of diseases caused by the lack of hygienic awareness. I think toilet can be considered as one of the most important items that is used by most people in developed countries in a daily bases. The use of toilet is a symbol of a civilized society that is organized in which it has a integrated sewage system.

Before the arrival of toilet, ancient civilizations often dumped their human waste randomly on the road and therefore caused the widespread of diseases such as cholera and diarrhoea. People didn’t understand the negative impacts of the germs and the life expectancy was relatively low. Nevertheless, after the toilet was widely adapted, people had less health concerns and the standard of living of the societies increased. Toilet is a significant artifact that marks one of the greatest turning point in the world history in which human became more civilized.

SPICE

Interaction between human and the environment- demography and disease: When the living condition improves, population increases due to higher life expectancy. Human waste is processed through the sewage system before being thrown into the environment and therefore reduced environmental pollution.

Cultural- science and technology: Toilet is a scientific innovation that was invented when ancient people finally realized the importance of a effective sewage system. This symbolizes the start of a more modern and advanced society.

Economic- trade and commerce: In the modern era, companies sought to make profit by improving the traditional flush toilet and transform it into multi-purpose toilet that includes additional features that makes sitting on a toilet a more enjoyable experience.

Period six- online shopping

Online shopping is a form of electronic commerce which allows consumers to directly buy goods or services from a seller over the Internet using a web browser. An online shop evokes the physical analogy of buying products or services at a retailer or shopping centre. Purchases can be paid via credit cards and other source of online banking account. The categories of products is wide and included all source of goods such as food, clothing, furniture etc. I think online shopping can be considered as one of the most important artifacts in the 21th century in which it creates a more convenient method for consumers to purchase goods.

The evolution of shopping originated from the ancient period when consumers bought products in concentrated trading area such as markets. Markets eventually expanded and became larger trading centres that involved a wider variety of goods. The development of shopping accelerated after the formation of department stores. Products are now organized into categories and searching for products becomes a lot more efficient.

Finally, the arrival of online shopping enabled consumers to shop without even physically leave their bed. This is a significant evidence of the advancement of world-wide transportation technology. Moreover,

companies gain more profit as the expenses of maintaining actual stores reduce.

SPICE

Economic- Industrialization: The transition from actual stores to online stores is a proof of further industrialization. As internet became extremely convenient, the relationship between producer and consumer changed from face to face to electronically contact.

Cultural- Science and technology: To Online shop, all you need is to click on the computer and the electronic system will deliver your order to the company. Products can now be shipped from one side of the world to the other side in less than a few days thanks to the advanced transportation system.

Period six- fridge

Domestic fridge is a machine for keeping things cold. It is sometimes called a fridge or an icebox. People put food and drinks in it, to keep those items cold or good (unspoiled) for a longer time. The history of artificial refrigeration began when Scottish professor William Cullen designed a small refrigerating machine in 1755 although it wasn’t widely used. The first refrigerator to see widespread use was the General Electric "Monitor-Top" refrigerator introduced in 1927.

Before the invention of the refrigerator, ice houses were used to provide cool storage for most of the year. Placed near freshwater lakes or packed with snow and ice during the winter, they were once very common. However, after the arrival of fridges, food can be preserved for a longer period of time without relying on the nature. The refrigerator increased the efficiency of the icebox while ending the problem of melting ice in the kitchen. The invention of the refrigerator raised the quality of life for many people in the new urban cities that were emerging at the beginning of the 20th century, simply because it offered people the opportunity to eat better foods.

The widespread of fridges allowed people to buy and store fresh food products in a safer environment. As a result people were able to consume better foods for example fresh produce, eggs, and meats. Moreover, the mass production of fridges in the assembly line contributed to the economic prosperity as a wide range of industries required fridges. Fridge plays a significant role in our daily life in which food becomes easy-reached and it makes our life more convenient.

SPICE

Interaction between human and the environment- science and technology: the invention of fridges extend the duration of food and replace the traditional ice houses. We can tell from the invention that people at the beginning of 20th century already had an excess of food in which a better way of food preservation was needed.

Social- The quality of life improved due to the mass migration from rural to urban areas encouraged by better foods.

Economy- Fridge industries made a large amount of profit due to the widespread of fridges in both industries and individual houses.

Period five- automobile

A car is a vehicle used to transport passengers. Cars usually have four wheels and an internal combustion engine. The earliest automobiles recorded were actually steam engines attached to wagons in the late 18th century. The steam engines were heavy and therefore the wagon was slow and hard to control. Better and faster steam cars became common late in the 19th century.Karl Benz invented the modern automobile. He used a four-stroke type of internal combustion engine to power his "Motorwagen". He began to sell his production vehicles in 1888.

During the period of industrialization, the first affordable automobile called Ford Model T was massively produced and people could then travel to any places that they wish without relying on public transportation. The automobile industry gained a huge amount of wealth as  the demand for cars increased when people discovered its convenience. The arrival of car also signified a greater damage to the environment in which carbon dioxide is directly polluting the air.

Automobile represents a turning point in the history of transportation technology. Not only did it enabled faster travel and more convenient transportation, it accelerated the pollution to the environment. However, despite its negative impact, automobile does makes trade, commerce, and transportation a lot easier compared to ancient technology such as lateen ship and camel saddles. I think it is an artifact that must be included in period five due to its significant contribution since the industrialization until today.

SPICE

Interaction between human and environment- technology: The negative impact of automobile is that it pollutes the environment by spreading CO2 into the air. Resolution such as the invention of electronic automobile is taking place to decrease the damages caused by steam cars.

Cultural- With the widespread of automobiles, people could travel to more places and the interaction between people in different region increased.

Economic- industrialization: Automobile is definitely one of the most important inventions created during industrialization that changed the way people and goods move.

Period five- Theory of Special Relativity

The theory of Special Relativity explains how to interpret motion between different inertial frames of reference— that is, places that are moving at constant speeds relative to each other. Einstein says it's impossible to determine if you're moving unless you can look at another object. It also shows that measurements of distance and time depend on how fast you are travelling. This means that if someone your age goes into space for ten years and travels millions of miles, that person will come back looking two years younger than you!

The highlight of the theory is that it marked the beginning of modern physics, the post-Newtonian conception of physics that deals with the underlying structure of the smallest particles in nature. The discovery of special relativity is significant in the way in which scientists began to study on the more fundamental concept of physics instead of the more large-scale and easy-to-observed ideas such as force. This suggested that technology had took a further step towards advancement, which allowed more intricate scientific study.

The applications to nuclear energy production and synchronization of the global positioning system (GPS) satellites around the earth indicate an effect of relativity on our day-to-day activities. The military and combat today of nuclear warheads and nuclear-powered submarines rely on relativity through GPS. However, GPS enables not only the Department of Defence, but also the commuter who has just taken a wrong turn and the couple searching for a restaurant.

SPICE

Cultural- science and technology: The theory of Special Relativity changes the way human had been viewing the world around them. When a person is “running”, the observer can be considered as the one that is “running” and the runner can be considered as the motionless one. This idea amazed me and led to further study of the movement and motion of human.

Interaction between human and the environment- technology: The invention of GPS makes traveling in unfamiliar area a lot easier and it’s more efficient than traditional maps. Moreover, the GPS function in electronic products allow people to find them when they are lost. GPS is also a helpful tool used by the police to locate criminals.
