This article discusses the reasons why some flowers close up at night while others stay open. The timing of flower opening often relates to the pollinators they hope to attract, with bees and hoverflies being active during the day and moths being active at night. Flowers may close at night to protect nectar from thieves, prevent pollen from getting wet, and control temperature. Additionally, some flowers open at night and remain open all the time, producing perfume only at night. The article also explains the accuracy of atomic clocks, stating that the claim of a clock ticking for 40 billion years without losing a second is a metaphor to convey its accuracy. Lastly, the article mentions the possibility of creating microscopic atomic bombs and the potential use of matter-antimatter weapons in science fiction and space travel. [Extracted from the article]
