Tidak ada apple yang jatuh atas kepala Sir Isaac Newton, contoh dibuat supaya pelajar mudah faham, dia cuma mengkaji kenapa buah apple jatuh lurus tidak condong ke kiri atau ke kanan, terapung atau ke atas, kemudian membuat kesimpulan tentang graviti. Pokok tersebut masih ada hingga sekarang setelah 357 tahun

There’s no evidence to suggest the fruit actually landed on his head, but Newton’s observation caused him to ponder why apples always fall straight to the ground (rather than sideways or upward) and helped inspired him to eventually develop his law of universal gravitation.

2011, Bencana nuklear Fukushima, lebih 500 warga emas Jepun termasuk wanita, berumur lebih 60 tahun menjadi sukarelawan, membantu membersihkan kesan radioaktif. Kata mereka “Generasi kami yang membina loji ini, kami harus bertanggungjawab agar generasi akan datang selamat”. Warga emas bekorban untuk generasi muda.

During the 2011 Fukushima nuclear disaster, over 500 Japanese seniors, all of them over age of 60, come to help clean up the radioactive zone.

They are all retirees, and they have all volunteered for a single, dangerous mission: to replace younger workers at the badly damaged Fukushima nuclear plant.

The Skilled Veterans Corps for Fukushima consists of more than 500 seniors who have signed up for a job that has been called courageous — and suicidal.

Kazuko Sasaki, a 72-year-old grandmother, is one of those ready to serve.
“My generation built these nuclear plants. So we have to take responsibility for them. We can’t dump this on the next generation,” she says.

Gempa bumi dasar laut bermagnitud 9.0 serta tsunami yang menyusulinya membawa kemusnahan besar sehingga 16,000 orang terbunuh dan ramai yang dilaporkan hilang.

Badai tsunami dahsyat itu yang mencapai ketinggian 15.5 meter menyebabkan kemusnahan besar pada Loji Janakuasa Nuklear Fukushima Daiichi 4,700MW yang terletak di pantai wilayah Fukushima dan menyebabkan sisa radioaktif merebak ke persekitaran.

Hari ini tempat yang terjejas kerana gempa bumi dan tsunami hampir pulih sepenuhnya. Sehinggakan kawasan yang terjejas kerana kesan radioaktif, di luar lingkungan 12 kilometer (km) dari reaktor Fukushima, kehidupan beransur pulih.
