When I was in the Navy, the officer in charge of our Navy SH-2F Seasprite helicopter crew, Lt. Cmdr. Chuck Taylor, briefed us before we flew off the back of frigates and destroyers, and the subject of air density was often discussed. Here’s why: Helicopters fly by chopping the air; the denser the sky, the more efficient the rotors become and the less power they need from their jet engines.
It’s been said that creatures, on average, have somewhere around 1 billion heartbeats over a lifespan. The theory is that the bigger the animal, the slower its heartbeat. Consequently, the longer it will live.A blue whale has an average heart rate of less than 20 beats per minute as it swims through the ocean with slow grandeur with an average lifespan of 80 years.A house cat has a heart rate of around 150 beats per minute with a typical life span of 15 years.
Here is this week’s weather forecast by PG&E meteorologist John Lindsey. Santa Lucia (northeasterly) winds will bring mostly clear skies and warmer conditions to the coastal regions of San Luis Obispo County; however, dense ground fog will continue to develop in the inland valleys during the night and morning hours, burning off to hazy sunshine in the afternoon.
Please be especially careful if traveling to the coastline to observe the biggest waves of the year. Never turn your back on the ocean, as sneaker waves as high as 25 feet can drag you into the sea. The swell will rapidly build later this morning into this afternoon. @CALFIRE_SLOhttps://t.co/L2FUO7ZvOp

Muck Rack makes it simple to find people, tweets, or articles that mention any name, keyword, company, hashtag etc. We've compiled this guide to help you make the most of your search.
Selecting a term
Start searching tweets, articles from media outlets, articles mentioned in tweets, journalists'
names, titles and bios with some suggested searches:
Companies or Topics (e.g. iPhone, Microsoft)
Phrases (e.g. "cloud computing") — use quotes to keep the terms together
Twitter handles (e.g. @username) — returns those who have mentioned or replied to
Names (e.g. "David Pogue")
Hashtags (e.g. #sxsw, #london2012)
Bio details (e.g. vegan, Olympics, father)
Muck Rack's Advanced Search allows for many boolean operators.
Find results that mention multiple specified terms, use AND or
+. For example, ensure each result contains both Elon Musk and Mark Zuckerberg by
searching Musk AND Zuckerberg or Musk + Zuckerberg.
Use the operators OR or , to broaden your search when you'd like either of
multiple terms to appear in results. (This is the default behavior of our search when no operators
are used). For example, results will contain either cake or cookie by searching cake OR cookie or cake,cookie
Use NOT or - to subtract results from your search. For
example, searching Disney will yield results about the Walt Disney Company as well as Walt Disney
World Resort. To exclude mentions of Disney World, search for Disney -World or Disney
When using one of these operators with a phrase, enclose it in quotation marks. For example, you can
find results about smartphones excluding Apple's iPhone 4S by searching smartphone -"iPhone
Exact case matching or punctuation
If you're searching for a brand name or keyword that relies on specific punctuation marks or capitalization, you can
find results that match your exact query by adding matchcase: before the keyword you're searching for, like matchcase:E*TRADE .
Use parentheses to separate multiple
boolean phrases. For example, to find journalists talking about having fun in Disney World or
Disneyland, search for ("disney world" OR disneyland) AND fun.
An asterisk can be used to search for any variation of a root word truncated by the asterisk. For example, searching for admin* will return results for administrator, administration, administer, administered, etc.
A near operator is an AND operator where you can control the distance between the words. You can vary the distance the near operation uses by adding a forward slash and number (between 0-99) such as strawberries NEAR/10 "whipped cream", which means the strawberries must exist within 10 words of "whipped cream".
