Description
Crooke's Solar Radiometer, Short Blue Stem, Clear GlobeSolar radiometers are also known as light mills because light moves their blades as opposed to wind for windmills. They consist of an airtight bulb containing a partial vacuum. Inside the glass bulb is a fine vertical spindle with a set of vanes mounted at the top. When the glass bulb is exposed to light, the vanes are propelled around, the speed of propulsion increases with the intensity of light, providing a qualitative way of measuring

Loving this book
Format: Hardcover
When I woke up this morning I felt a real desire to write a review about this book.
When I bought it I was intending for it to be a daily reflection. I wanted something that would be manageable and would feel like an infusion of loving self care.
Even though I am only on page 104, I look forward to reading just one page. Then I find myself reading a second page, a third page, a fourth page...
Recently I read a post by Brene Brown that talks about "microdosing hope" during tough times.
Nedra Glover Tawwab microdoses the reader with hope, love, kindness, peace, compassion, healthy boundary setting, and recommitment of our vows to ourselves.
She offers these reflections in a way that you feel like you are talking to a good friend. Gentle and loving. Some reflections are reminders for me. Some share new information. Some offer suggestions on how to do boundaries and self care in new ways.
I highly recommend this book. Like me, it might be hard for you to stop at just one page...
