Homeostasis

Homeostasis does not imply that a given physiological function or variable is rigidly constant with respect to time, but that it fluctuates within a predictable and often narrow range. When disturbed up or down from the normal range, it is restored to normal.

Proper Use

The Canon EF-S 18-55mm f/3.5-5.6 IS II lens is designed to be used with autofocus mode, and it should not be damaged if you turn the focus ring while the lens is in autofocus mode. However, it is not recommended to do so as it can cause the autofocus motor to work harder than necessary, which can lead to faster wear and tear of the motor. If you need to adjust the focus manually, it is best to switch the lens to manual focus mode first before turning the focus ring. This will allow you to adjust the focus without putting any additional strain on the autofocus motor.

《鄂圖曼帝國五百年的和平》

十四世紀初葉,在安納托利亞邊境誕生的小國——奧斯曼公國,發展成覆蓋巴爾幹、安納托利亞、阿拉伯世界、北非的大帝國——鄂圖曼帝國。至十九世紀為止,鄂圖曼帝國在橫跨約五百年的時間,管理多民族與多宗教,實現長期的安定,使得東西文明的界限日趨模糊。爾後,鄂圖曼帝國又延續了近百年,直到一九二二年方才落幕。

Non-nuclear weapon test

On October 18, 2023, the United States conducted a high-explosive experiment at a nuclear test site in Nevada. The experiment was conducted to improve the country’s ability to detect low-yield nuclear explosions around the world. The experiment used chemicals and radioisotopes to validate new predictive explosion models to devise (設計) a method of detecting atomic blasts in other countries. The United States Energy Department, which oversees (監督) the stockpile (儲備物資) of more than 5,000 nuclear weapons, stated that this method would also be able to detect sub-critical experiments, which are small-scale explosions that verify weapon designs without the amount of atomic material needed to sustain a chain reaction.

Hours before the test, Russian officials announced that they planned to revoke (廢除) the ratification (正式簽署) of a ban on atomic weapons testing. The lower house of Russia’s parliament passed a bill on October 18, 2023, revoking Russia’s ratification of the Comprehensive Nuclear Test Ban Treaty (CTBT). The CTBT prohibits all nuclear explosions in all environments, for military or civilian purposes. The United States signed the CTBT in 1996 but has not ratified it yet.

The future of DSLR cameras

The future of DSLR cameras is uncertain as mirrorless cameras are becoming more popular and offer many advantages. Mirrorless cameras are lighter, more compact, and have faster autofocus systems. They also offer better image stabilization and greater dynamic range. Despite this, DSLR cameras may still have some loyal users and some potential improvements, such as more advanced autofocus systems, better image stabilization, and faster shooting speeds. Artificial intelligence technology may also play a role in enhancing DSLR performance and usability.

It’s worth noting that DSLRs still make up more than 53% of today’s camera sales. However, the industry is moving towards mirrorless cameras, which are expected to become the norm in the future.

In conclusion, while the future of DSLR cameras is uncertain, they will likely continue to be used by some photographers who prefer their unique features. However, mirrorless cameras are expected to become more popular in the future due to their many advantages.

珍貴回憶的抽屜

請問大家,家中有沒有一個抽屜,擺放自己珍貴的物品?那些物品不必是價值不菲,但失去了卻很困難才能再擁有。五年前,我搬家時掉去很多雜物,有不少珍貴的物品卻移轉到新居床下的一個抽屜。讓我介紹幾件給大家看看︰


小六紀念冊,封面有外星人、UFO、地球和木星,與「我的志願」天文學家相吻合。內頁是有排序的,最喜愛的老師、同學排到最前,真的很膚淺。中五紀念冊是求其買的,朋友說那個卡通是紅十字加 Qoo 的合體版,內頁是根據英文姓氏次序排列。


小學同學仔在賣校服的地方搜購校章,貼在小學旅行合照上,然後送給我們,別出心裁。


未開封的富士 36 張 ISO 200 菲林,是歷史遺留下來的產物。舊相機印象中壞了後已掉棄,卻留下幾張沖晒後的 DVD。朋友說舊菲林相的微粒有其獨特之處。


一家人去外地的旅行計劃已擱置多時。大部分的輔幣是爸爸退休前到國外公幹,帶回來給我珍藏的。

何謂成功

雖說職業無分貴賤,但現實很殘酷,薪金有分高低。的確,有的工作較有使命感,有的工作較有挑戰性,但不要看輕任何一種工作,它們在一個社會上環環相扣。所謂行行出狀元,騎牛搵馬的心態不一定適用於每一個人。沒有專業知識,又想轉行加人工,未免過於天真。要在一個行業上不斷努力也不足夠,要留意溝通技巧。辦公室政治不可不理,如處理不到只能選擇沉默是金。

很慚愧地說,我對朋友們嚴重缺乏了解。可能,這是現世代的通病。社交媒體的出現,手機短訊的盛行,通個電話都是一個奢侈。看到往時的同學們出類拔萃,值得傲視同儕,卻不清楚他們付出過多少努力。現在已經沒有什麼疫情、沒有什麼社會運動,出來聚聚的機會卻要刻意營造。所以,了解他們的近況也不容易,更不要說深切關懷。

這個世代講求終身學習。普通話和電腦基本知識不可或缺。知識可以不斷累積,但只著重吸納幫助本業的技術,未免乏味。有時培養對自己有興趣的知識,會有意料之外的收穫。一個人要有多元化的知識,對工作來說亦然。

Spleen

The spleen is a fist-sized organ found in the upper left side of your abdomen, next to your stomach and behind your left ribs. It's an important part of your immune system but you can survive without it. This is because the liver can take over many of the spleen's functions.

Python Calculation

 

Formatted string literals (f-strings) let you include the value of Python expressions inside a string by prefixing the string with f or F and writing expressions as {expression}.

An optional format specifier can follow the expression. This allows greater control over how the value is formatted. The following example rounds pi to three places after the decimal:

>>> import math

>>> print(f'The value of pi is approximately {math.pi:.3f}.')

The value of pi is approximately 3.142.

Lab-grown diamonds are more environmentally friendly

長期以來,鑽石一直被視為女孩最好的朋友。 但它們從地下的開採破壞了我們與環境的關係。 開採一顆一克拉的鑽石可能意味著要去除數百噸的泥土,這個過程會消耗大量的淡水和化石燃料,還會產生其他副作用,包括森林砍伐和河流污染。

Diamonds have long been marketed as a girl's best friend. But their extraction from the ground has damaged our relationship with the environment. Extracting a single one carat diamond can mean the removal of hundreds of tonnes of earth, a process that consumes vast amounts of fresh water and fossil fuels, and has other side effects include deforestation and river pollution.

BBC

Lab-grown diamonds are generally less expensive than natural diamonds of comparable size and quality. They are also considered more ethical because they do not involve mining or human rights issues associated with diamond mining.

Deepfake

Deepfake refers to a specific kind of synthetic media where a person in an image or video is swapped with another person’s likeness. Deepfakes can be used to manipulate and threaten individuals and corporations. Deepfakes can be created using open source face-swapping technology. As deepfake technology improves, it gets harder to spot them.

Depth of field in terms of Optics

Depth of field is the distance between the nearest and farthest objects that are in acceptably sharp focus in an image captured with a camera. Depth of field is influenced by several factors, including the aperture size, focal length, and distance between the camera and the subject.

The physics behind depth of field can be attributed to the fundamental concept of the Circle of Confusion. It describes a point of light directed onto a camera's focal plane by the lens. The diameter of this dot of light might be extremely narrow when it hits the camera sensor, or it might be wider.

地緣政治的定義

地緣政治從字面來看,它是與地理、政治有關的課題。從深層角度來看,地緣政治則是以地理的宏觀思維來解釋一個國家的政治行為之科學。人與自然環境的關係是永久存在,地理環境對人類社會總會有一定的影響與制約。人類改造自然的能力正在不斷地提高,人對自然的認識也在不斷提昇。所以,地緣政治的觀點也隨著人類改造、認識自然而有所改變。

改編自臺灣國立政治大學網上文章

全球化重新改變了時間與空間的概念,卻仍舊無法擺脫國家控制領土、邊界及競爭概念。邊界仍然是地緣政治、國際關係與國家定義的核心。

在這個地理距離看似漸被消弭的世界,遠方戰事也透過經濟牽動著我們的日常生活,了解、預測世界局勢的變化走向,已成為現代人不得不面對的重要課題。
