歡迎閱讀《週末科學版》！我們每週五都要為你介紹可以在家中進行的有趣科學實驗。你可以在《科學日誌》中 記錄自己做了哪些活動，這樣就可以將所學的紀錄下來，比較這些結果，也許還可以利用它們來設計新的實驗！先看一下《科學日誌》的點子再開始吧。展開實驗之前，記得要獲得大人許可喔！
Today we’re going to build a viewer that focuses light in a similar manner to the human eye or a camera. When you use the viewer to look at the image of a candle, you’ll be able to see that the candle has been flipped upside down!
What you will need:
GRAPHIC: TAIPEI TIMES
An empty Pringles can
A marker
A knife that is able to cut the can
PHOTO: MICHAEL KEARNEY, TAIPEI TIMES
A thumbtack or something else that can poke a hole in the bottom of the can
Wax paper or a tissue
Tape
Aluminum foil or paper
A candle and a lighter
A dark room
► Draw a line around the Pringles can about 5cm from the bottom.
► Cut along the line.
► Use the thumbtack to put a small hole into the center of the bottom of the can. Have an adult help you with this part.
► Attach the plastic top of the can to the bottom portion of the can. If the top is clear, you’re going to need to attach a piece of wax paper or tissue to it.
► Tape the top of the can back onto the bottom portion.
► Cover the side of the can in aluminum foil or paper so that no light can get through.
► Have an adult help you light the candle. Turn off the lights in the room, and look at the candle through the top of the can. You should see an upside-down image of the candle. You might need to get the bottom of the can close to the candle to see it. Don’t forget to record what happens in your Science Journal.(michael kearney, staff writer)
今天我們要來製作一個和人類肉眼或是照相機聚光成像原理類似的觀景器，當你用這個觀景器來觀看蠟燭的影像時，你會看到一個上下顛倒的蠟燭！
所需材料︰
一個品客洋芋片空罐
一個做記號的筆
一把可以割開罐子的刀
一根圖釘或是其他可以把罐子底部戳洞的東西
蠟紙或是一張衛生紙
膠帶
鋁箔紙或是白紙
一支蠟燭或是一個打火機
一間暗房
►沿著品客罐底部往上算約五公分處劃一圈線。
►沿著畫的線裁剪。
►用圖釘在罐子底部中央戳一個小洞；請大人幫你做這個步驟。
►把罐子的塑膠�?b下半截罐口上；如果�?O透明的，你得加上一張蠟紙或是衛生紙。
►用膠帶把罐子的上半截和下半截重新固定回原樣。
►用鋁箔紙包裹住罐身，使光線無法透進罐子裡。
►請大人幫你點燃蠟燭，把房間的燈關掉，然後透過罐口觀察蠟燭，你會看到一個上下顛倒的蠟燭影像；你可能需要拉近罐底和蠟燭間的距離來看清楚蠟燭。別忘了將實驗結果記錄在《科學日誌》喔。 （翻譯︰袁星塵）
Even as he grows older, Microsoft founder Bill Gates still fondly remembers the catalytic computer code he wrote 50 years ago that opened up a new frontier in technology. Although the code that Gates printed out on a teletype machine may look crude compared to what’s powering today’s artificial intelligence platforms, it played a critical role in creating Microsoft in April 1975 — a golden anniversary that the Redmond, Washington, company celebrated on April 4. Gates, 69, set the stage for that jubilee with a blog post reminiscing on how he and his old high school friend — the late Paul Allen
Australia’s strict immigration policies have long been criticized, particularly for how they treat people with disabilities. Having been residents of Australia for years, Scottish Laura Currie and her Italian partner, Dante Vendittelli, recently experienced the impact of these immigration policies. Their son Luca, born in Australia and diagnosed with cystic fibrosis, became the reason their residency application was denied due to the anticipated high healthcare costs. Had Luca been healthy, there would have been no objections to their permanent residency. This case not only highlights discrimination against disabled individuals, but also raises questions about fairness and inclusion within Australia’s immigration
A: After holding nine concerts in Kaohsiung and Taipei recently, “God of Songs” Jacky Cheung will stage three extra shows later this week. B: They’re compensation for the three shows he postponed last year due to illness. A: He also canceled three more shows in Guangzhou last month. His health is worrisome. B: When touring Guangzhou, he dedicated his hit “She Is Far Away” to late singer Khalil Fong. That’s so touching. A: Online music platform KKBOX has also launched a campaign to pay tribute to Fong. I can’t believe he died so young: he was only 41. A:
The study had several issues. Small sample sizes made it hard to draw __7__ conclusions. Additionally, taking a __8__ like pure MSG on an empty stomach is likely to make a person ill in any case. Choosing individuals who already had a history of the symptoms could have created a bias because they were likely to __9__ the reactions again. When real scientific research on the effects of MSG was eventually done, many of the myths surrounding it were proven __10__. The U.S. Food and Drug Administration and other global organizations have found MSG safe to eat. Today, MSG
