Lilac flower cream

An ancient French technique, is the process of extracting a flower’s perfume into odorless animal or vegetable fat. The process used here is a simple method that will capture the of spring in a jar. The cream can be used directly on your skin or to flavor favorite sweet dishes. It is best to use the ’s tiny blooms straight from the shrub, picking them in the morning when they are the most fragrant.

From:
Harvest by Stefani Bittner

MAKES TWO 16-OUNCE JARS

32 ounces extra-virgin coconut oil

10 cups lilac blooms picked from the heads in 2 cup increments as needed

Pick 2 cups of lilac blooms. Place the coconut oil in a small saucepan and melt over low heat until it is completely liquefied. Pour the liquid into a 10 by 10-inch (25 by 25-cm) casserole dish and allow it to harden. After the oil has hardened, score it with a butter knife. This will help the scent of the flowers penetrate it more deeply. Layer the tiny lilac blooms onto the oil, covering it with 2 inches (5 cm) of blooms. Place a second 10 by 10-inch (25 by 25-cm) casserole dish upside down atop of the first one. Use electrical tape to seal the two dish edges tightly, and place the dishes in a dark area.

After 48 hours, remove the tape seal and discard the spent blooms. Pick another 2 cups of lilacs, add another 2 inches (5 cm) of flower blooms to the oil, and seal again for another 48 hours. Repeat this process three more times, for a total of five cycles with fresh blooms each time.

Scrape up the oil from the casserole dish, place it into two 16-ounce jars, and seal the lids. Store in a cool, dark place; the flower cream will keep for up to 3 years.

The Travel Diaries of Albert Einstein: The Far East, Palestine, and Spain, 1922 - 1923 by Albert Einstein & Ze'ev Rosenkranz, 2018

lbert Einstein's travel diary to the Far East and Middle EastIn the fall of 1922, Albert Einstein, along with his then-wife, Elsa Einstein, embarked on a five-and-a-half-month voyage to the Far East and Middle East, regions that the renowned physicist had never visited before.





 Einstein's lengthy itinerary consisted of stops in Hong Kong and Singapore, two brief stays in China, a six-week whirlwind lecture tour of Japan, a twelve-day tour of Palestine, and a three-week visit to Spain. 
This handsome edition makes available the complete journal that Einstein kept on this momentous journey.The telegraphic-style diary entries record Einstein's musings on science, philosophy, art, and politics, as well as his immediate impressions and broader thoughts on such events as his inaugural lecture at the future site of the Hebrew University in Jerusalem, a garden party hosted by the Japanese Empress, an audience with the King of Spain, and meetings with other prominent colleagues and statesmen. Entries also contain passages that reveal Einstein's stereotyping of members of various nations and raise questions about his attitudes on race. This beautiful edition features stunning facsimiles of the diary's pages, accompanied by an English translation, an extensive historical introduction, numerous illustrations, and annotations. Supplementary materials include letters, postcards, speeches, and articles, a map of the voyage, a chronology, a bibliography, and an index.Einstein would go on to keep a journal for all succeeding trips abroad, and this first volume of his travel diaries offers an initial, intimate glimpse into a brilliant mind encountering the great, wide world.

"I am convinced that the work in Palestine will succeed in the sense that we shall create in that country a unified community which shall be a moral and spiritual center for the Jewries of the world. (...) I believe that it is of infinitely greater importance that Palestine shall become a powerful moral and spiritual center for the whole of the Jewish people."

It has concise text highlighting ID criteria as well as notes on biology, habitat and conservation, along with stunning colour photographs and accurate range maps based on maps compiled by the Biological Record Centre.





The orchid family is one of the largest plant families in the world, reaching its highest diversity in the tropics where their exotic and colourful flowers are often truly breathtaking. Britain and Ireland have just 56 species of wild orchid, some of which are rare or scarce, whilst others are surprisingly inconspicuous. Yet, whether large or small, all orchids share flamboyant flower structures and incredible beauty.

What’s the world’s smallest cephalopod? That would be the southern pygmy squid (Xipholeptos notoides). Growing only about 0.9 in (2.5 cm) long, this diminutive critter can be found in the waters of the Southwestern Pacific near Australia. During the daylight, it clings to sea grass and stays out of sight. By night, it hunts for prey including small crustaceans like shrimp. Its lifespan is only about 150 days.

Minneapolis 槍擊事件後,大多數美國人對 ICE 持負面看法,並支持對該機構進行重大改革。

today.yougov.com/politics/arti

圖一:請問你認為 ICE 探員在 Minneapolis 槍擊該名女性時所使用的武力是否合理?
單論全國不分政黨傾向,就有過半 (53%) 的民眾認為該名殺死 Renee 的 ICE 探員不合理使用武力;相反的僅有 28% 的民眾認為這是合理的。

然後是政黨傾向,兩黨支持者我就跳過了,直接看圖就能懂,這邊重點是中立選民:
- 20% 認為合理
- 23% 不知道或不表態
- **58% 認為不合理**

圖二:你認為 ICE 探員應該因為在 Minneapolis 槍殺該名女子而面臨刑事指控嗎?
同樣的,全國人民直接過半都同意該名 ICE 探員應該要受到刑事指控,就連中立選民也是過半同意。

圖三和圖四要配著一起看:有超過 2/3 的全國人民都同意招募 ICE 探員的程序上必須要有更嚴格的要求,圖四第一條線就顯示了,連 47% 的共和黨支持者都同意這點。

Pictured is a 430 million-year-old Silurian Dalmanites caudatus from England. This 2.5-in- (6.4-cm-) long specimen was preserved in rock that, when carefully opened, revealed positive and negative splits! Notice that this trilobite is slightly disarticulated? A small brachiopod shell became wedged between the trilobite's head and body, causing them to separate.

Image Description
On the left is the positive split: A brown trilobite fossil is protruding from the surface of a beige stone. The trilobite has an oval-shaped body with a ribbed carapace; its head is smooth and rounded; its hind-end has a sharp point. On the right is the negative split. An indentation of the trilobite fossil can be seen in the stone; there's also a sea shell on the upper-half of the stone.

看到有人说既然能产检出孩子唇腭裂,为什么不打掉的言论(是最近的嫣然医院新闻下面的评论)。产生了一些想法,记录一下。

我们这一代是在优生优育的宣传语中长大的,ableism 贯穿整个中国社会的价值观。不仅仅是残障人士,你老你弱你女,都是被判定为没有什么存在的价值的。
但是就在优生这一块上,我也没有办法完全站在道德制高点上批判那时候的能力主义,天真地说“任何筛选都是歧视”。在社会没有办法提供任何保障,照顾责任被私有化,并由女性承担和兜底的时候,优生的确是一个粗暴但是有效的“用筛选代替保障”的系统性解决方案。但是问题在于,现在中国社会至少是可以包容一部分这些差异了,这个制度性的能力主义还是深入人心,还是有人能肆无忌惮地说出“生下来就是害人害己”,或者“就应该打掉”这种话。
这就是为什么我听到上野老师说“女性主义是追求弱者也能得到尊重的思想”的时候非常触动——尊重不是给强者的奖励。这个伦理承诺对我一个在“优生优育 + 能力主义 + 性别压迫”中长大的人来说,真的太陌生了。

然后再说回产检,产检的目的不是筛除不完美生命,而是提供信息,让人在知情的情况下做出选择。这里的选择是 pro choice,而不是 pro-normative outcome。如果只有“最不弱的选择”才被尊重,那女性从未真正拥有选择。

"There are no written documents, it's only that a boat landed there hundreds of years ago, but we had boats landing there, also."

"I have done more for NATO than any other person since its founding, and now, NATO should do something for the United States. The World is not secure unless we have Complete and Total Control of Greenland. Thank you! President DJT."
