A large number of inventions require years of arduous research and development before they are perfected. For instance, Thomas Edison had to make more than 1,000 attempts to invent the incandescent light bulb before he finally succeeded. History is replete with numerous other examples of people trying, yet failing to make inventions before they eventually succeeded. Yet some inventions have come about not through hard work but simply by accident.
In most cases, when someone unintentionally invented something, the inventor was attempting to create something else. For example, in the 1930s, chemist Roy Plunkett was attempting to make a new substance that could be used to refrigerate items. He mixed some chemicals together. Then, he put them into a pressurized container and cooled the mixture. By the time his experiment was complete, he had a new invention. It was not a new substance that could be used for refrigeration though. Instead, he had invented Teflon, which is today most commonly used to make nonstick pots and pans. Similarly, decades earlier, John Pemberton was a pharmacist in Atlanta, Georgia. He was attempting to create a tonic that people could use whenever they had headaches. While he was not successful in that endeavor, he managed to invent Coca - Cola, the world - famous carbonated soft drink.
Scientists have also made crucial discoveries by accident when they were conducting experiments. In 1928, Alexander Fleming discovered penicillin, an antibiotic, in this manner. He discovered some mold growing in a dish with some bacteria. He noticed that the bacteria seemed to be avoiding the mold. When he investigated further, he determined some of the many useful properties of penicillin, which has saved millions of lives over the past few decades. Likewise, in 1946, scientist Percy Spencer was conducting an experiment with microwaves. He had a candy bar in his pocket, and he noticed that it suddenly melted. He investigated and learned the reason why that had happened. Soon afterward, he built a device that could utilize microwaves to heat food: the microwave oven.

Dịch bài đọc:
Một số lượng lớn các sáng chế đòi hỏi nhiều năm nghiên cứu và phát triển gian nan trước khi chúng được hoàn thiện. Thí dụ, Thomas Edison đã phải cố gắng hơn 1.000 lần để sáng chế ra bóng đèn sáng trước khi cuối cùng cũng thành công. Lịch sử có rất nhiều ví dụ khác của những người cố gắng, nhưng không thể làm sáng chế trước khi họ cuối cùng đã thành công. Tuy nhiên, một số sáng chế đã đến không phải thông qua công việc khó khăn, nhưng do tình cờ.
Trong hầu hết các trường hợp, khi người nào đó vô ý phát minh ra điều gì đó, nhà phát minh đã cố gắng tạo ra một thứ khác. Ví dụ, trong những năm 1930, nhà chế tạo thuốc Roy Plunkett đã cố gắng tạo ra một chất mới có thể sử dụng để làm lạnh các vật dụng. Ông pha trộn một số hóa chất với nhau. Sau đó, ông đưa chúng vào một thùng chứa áp lực và làm mát hỗn hợp. Đến thời điểm thử nghiệm của ông đã hoàn thành, ông đã có một phát minh mới. Nó không phải là một chất mới mặc dù có thể được sử dụng cho tủ lạnh. Thay vào đó, ông đã phát minh Teflon, ngày nay được sử dụng phổ biến nhất để chế tạo các chậu và chảo không dính. Tương tự, nhiều thập kỷ trước đó, John Pemberton là một dược sĩ ở Atlanta, Georgia. Ông đã cố gắng tạo ra một loại thuốc mà mọi người có thể sử dụng bất cứ khi nào họ bị nhức đầu. Trong khi ông không thành công trong nỗ lực đó, ông đã thành công trong việc sáng tạo ra Coca-Cola, nước uống có ga nổi tiếng thế giới.
Các nhà khoa học cũng đã có những khám phá quan trọng một cách tình cờ khi họ tiến hành các thí nghiệm. Năm 1928, Alexander Fleming phát hiện ra penicillin, một chất kháng sinh, theo cách này. Ông phát hiện ra một số nấm mốc phát triển trong một món ăn với một số vi khuẩn. Ông nhận thấy rằng vi khuẩn dường như tránh nấm mốc. Khi ông điều tra thêm, ông đã xác định một số tính chất hữu ích của penicillin, điều này đã cứu sống hàng triệu người trong vài thập kỷ qua. Tương tự như vậy, vào năm 1946, nhà khoa học Percy Spencer đã tiến hành thí nghiệm với lò vi sóng. Anh ta có một thanh kẹo trong túi, và anh nhận thấy nó tan chảy. Ông điều tra và học được lý do tại sao điều đó đã xảy ra. Ngay sau đó, ông đã chế tạo một thiết bị có thể sử dụng lò vi sóng để nướng thức ăn: lò vi sóng

Rain pounded down on the roof. I was trying to read but the sound was too loud. I couldn’t help myself from being a little grumpy. I wanted to be outside playing, but the rain was keeping me inside.
My mom had gone to the grocery store, and my dad was spending Saturday at the office. I had planned to spend the day hiking, but Mother Nature decided that today was the perfect day for rain.
It meant that I would have to entertain myself. I spent most of the morning playing with my stuffed animals and reading. I was sitting next to the window staring out when I got a strange idea: why not just go outside anyway?
I put on my boots and a big raincoat and stepped out into the wet world. It was raining hard but it wasn’t cold. All I could hear were raindrops and the wind. I decided to go on my hike anyway.
My feet didn’t make any sound on the wet ground and the forest seemed different. I went to my favourite place and sat down. In the summer, my best friend Ellen and I would come here and sit for hours. It was our special place. All of a sudden, I thought I heard someone shouting my name. I turned and saw Ellen walking up behind me.
“Oh my Gosh! It’s really you, Martha!” she said. “I can’t believe that you are out here right now. I thought I would be the only person crazy enough to go for a walk in the rain.”
I was very happy to have some company. We decided that hiking in the rain was just as fun as hiking in the sunshine. We planned on hiking in the rain again.
