The History of KAYAKS

Canoeing and Kayaking go back to the dawn of human culture. The word "kayak" literally means "hunter's boat." The kayak was used for transport, but it was a miraculous hunting tool, facilitating a quiet approach towards one's desired prey. The covered deck of the kayak made it more sea-worthy and better able to shed waves than the traditional canoe. Kayaks are mostly used during summer months, primarily for hunting and fishing. 

Similar to the kayak, the umiak is a larger boat which can carry up to 20 people. The umiak and the kayak existed side by side, both finding useful niches for transporting and hunting throughout history. 

Kayak design varied according to the specific needs of inhabitants of particular regions. For instance, early kayaks designed by inhabitants surrounding the Bering Strait were wider and shorter. Whereas the kayaks from Greenland were sleek and low. Kayaks from Baffin Island were wider and longer. 

The kayak was first created by the Inuit, an artic people. Interestingly, despite being the birthplace of the kayak, very little archaeological evidence of the covered kayak can be found on the Siberian Coast.

Early Eskimos made kayak frames using driftwood, and early kayaks were wrapped in sealskins. 

In fact, most early kayaks were fabricated using wood for the frame and then tied together using sinew, or tendons, with a sealskin cover. Kayaks were virtually unsinkable with air-filled seal bladders. Today, very few traditional skin kayaks are still in use and the knowledge of their construction is quickly fading. Other early kayaks were made from whalebone or driftwood. 

The materials that have been used to make a kayak have changed significantly over the years. Europeans eventually discovered the versatility of the kayak, and kayaks once designed with sealskins were designed by Europeans with fabric covers. This method continued until the 1950's when a company known as Valley Products began producing the first fiberglass kayak. Then in 1984, the first plastic kayak was introduced. Kayaks continue to become lighter, sturdier, and more versatile. 

Now there are several types of kayaks designed with various materials suitable for a variety of sporting events. Today, kayaking is accessible to all skill levels, providing a quiet and gas-free form of breathtaking travel, exploration, and exercise.

Why You Should Take a Wine Country Tour

Are you a wine drinker?  If you are, have you ever thought about the history of wine, such as how it is made or why wine drinking and tasting is known as a popular activity?  If you have, you may want to plan a visit to wine country.  With that being said, a “traditional,” visit isn’t all that you should do, you should also take a wine country tour.

As nice as it is to hear that you should visit wine country and take a wine country tour, you may be wondering why.  After all, depending on where you live, you may need to travel quite far to visit an area that is referred to as wine country.  After a close exanimation, you will see that there are a number of reasons why you should not only visit wine country but also take a wine country tour.

One of the many reasons why you should arrange to take a wine country tour is because of the options you have.  For starters, wine country is a phrase that is used to describe an area that is known for their production of wine. When many of us think of wine country, California, namely Northern California, is often what first comes to mind.  With that said, there are other areas in the United States that are commonly referred to as wine country as well, such as part of New York State and Washington State.  Many of these other areas and their wineries also offer tours for wine enthusiasts.

As previously stated, depending on where you live, you may have to travel quite a distance to arrive at California’s wine country or another state’s wine country.  Even so, you are still urged to examine your options.  This is because wine tours make for great vacations.  Depending on where you visit, you can spend a few hours touring local vineyards and wineries or you can spend a few days doing so.  Also, in terms of being a great purpose for being a vacation, many of the communities surrounding well-known vineyards and wineries have an unlimited number of fun activities, such as hiking and dancing, as well as affordable overnight accommodations.

Returning back to the options that you have, it is important to know that wine tours come in a number of different formats. Guided wine tours are perfect for tourists who want to see the “best parts,” of wine country, as well as those who are unfamiliar with the area or may not have their own mode of transportation.  Although you will find some variations, many guided wine tours have tourists meet in a public place and then travel is provided, often by van or bus.

Although guided wine tours are popular with tourists, there are many more individuals, including both tourists and locals, who are interested in taking independent wine country tours.  Independent wine tours are ideal for wine enthusiasts who want to enjoy wine and its history without feeling rushed or pressured by other tourists and tour guides.  Most wineries and vineyards in California, as well as Washington and New York, have open doors.  If not, information on ideal times for visiting should be readily available online.  This information is typically posted to prevent conflict with planned events, such as weddings.



For the most part, tourists find that taking wine tours are affordable.  Many wineries and vineyards provide free access to visitors, but there are no guarantees.  For the most part, the costs associated with wine tours comes from wine tasting, which is a must do.  However, you still shouldn’t have to be worried about the costs.  Most wine country wineries and vineyards have affordable wine tasting rates, which are typically between five and fifteen dollars per person.  As for taking a guided wine tour, you will likely be charged a fee, but your fee may include wine tasting at a number of wineries along the way.

Perhaps, the greatest reason why you should take a wine country tour is that it is an experience that you will never forget.  Not only are wine tours fun for wine drinkers, but they are also enlightening and educational in nature.

Jordon and Ali

Muhammed Ali - Photo: Pixabay
Throughout black history, great black athletes have served as role models to America’s youth, in a way that may not have been possible for others leaders.  And to be sure, some of these great heroes of athletics have become virtually godlike to all sports fans, not just those in the black community.  Michael Jordon’s ability on the basketball field during his career at times seems to be virtually superhuman.  And the career of Mohammed Ali sent such a powerful message of black pride to black and white America that he virtually transformed the social perception of the black man through sheer talent and attitude.

Before Mohammed Ali came along, the idea of a black boxer, even a very good black boxer becoming such a central figure for black pride seemed unlikely.  But Ali demonstrated something to the youth of the African American community that was so inspirational that it helped to transform their worldview like no other public figure could have done.  

With his swagger and braggadocio, Ali stood out as a proud black man in such a way that had never been seen before.  His use of rhyme with such phrases as “I float like a butterfly and sting like a bee” to his self-promotion maintaining “I’m pretty”, that sent a message to black and white admirer alike.  And that message was loud and clear.  Ali was black and he was proud and other black men and women in America have just as much reason to be proud as he was.

This was an important message because coming out of years of oppression, it was sometimes difficult for black youth to gain a sense of pride and the self-assurance needed to get out there and be a success.  It took the work of great black role models such as Mohammed Ali to let them know that it is allowable for you to be proud and to be great as well.  For Ali didn’t back up his claims with just boasts.  He was truly a great black athlete as well.  So when Ali bragged that he was “pretty”, he showed that the way he fought truly was a thing of beauty.

That same excellence and how it has been used to inspire the black community can be found in the phenomenal career of Michael Jordon.  In the same way that Ali’s talent seemed to eclipse even the genre of boxing, Jordon was so phenomenal at basketball that he became an icon of excellence and skill and a role model for black youth across the country.  Both of these men recognized that God had given them this tremendous talent and the opportunities to reach their potential.  And they worked hard to be a role model to their community so others would be inspired to be their best as well.  

Moreover, great black sports heroes also provided healing by setting a high standard of excellence for sports fans of all races to admire.  It wasn’t just black sports fans who adored the work of Mohammed Ali and Michael Jordon.  They became true heroes to anyone to whom sports was an important part of life.

Sport is an arena where men and woman can come to socialize and find common ground.  Like entertainment, there is a world of sports that make comrades of all who enjoy the exploits of sports heroes whether on the baseball diamond, the football field, the boxing arena or the basketball stadium.  And sports fans have a standard that they value their heroes that is based on talent, achievement, and ability to do that one thing everybody in sports admires – to be a winner.  And Mohammed Ali and Michael Jordon were certainly the embodiment of great black men who were also in every way winners.  And we all admire that regardless of race, color or creed.

A Little Red Wine Could Take You A Long Way!

Longevity interests a lot of people who aren't ready to give up their lives, just yet, and who look to healthy alternatives to culturally defined eating patterns and "health care."

The benefits of drinking wine have been touted for a while and are thought, by some, to be the reason why the French can get away with eating a high-fat diet while enjoying a low rate of coronary disease.

A few years ago, a study by French research team also found that men who regularly drank at least two glasses of wine daily were 50 percent less likely than non-drinkers to suffer a second heart attack.

Previous studies with yeast, a small species of worm, and fruit flies have shown that resveratrol -- a polyphenol antioxidant found in grapes, especially red grapes, and particularly pinot noir grapes which are grown in northern latitudes and used in wines coming from New York, Washington, and Oregon -- is a life-extending compound.

In a new study from Italy, resveratrol has been used to increase the lifespan of a short-lived breed of tropical fish by more than 50%. Not only did fish given resveratrol in their food live longer than the control group, they stayed livelier as they aged and displayed better memory in stimulus/response tests. And the neurons in their brains didn't decay as quickly when they died and were dissected.

Resveratrol, an organic compound contained in the skins of grapes that protects them from disease, is extracted from grapes by the winemaking process. The wine becomes a preservative for the resveratrol and prevents its oxidation.

That's why drinking grape juice or eating raisins doesn't have the same effect; the resveratrol has neither been extracted nor preserved. It's also been shown that resveratrol in food supplements oxidizes upon exposure to air and loses its effectiveness.



Red wine may truly be a "wondrous drug!"

Other studies have shown that wine, especially red wine, can help prevent colds, increase the levels of HDL (good) cholesterol, lower the risk of Alzheimer's, reduce the size and number of fat cells in the body, reduce the risk of prostate cancer, and has anti-inflammatory properties to boot.

Drug companies are trying to copy Red wine may truly be a "wondrous drug!", but might not be able to preserve its health-preserving benefits. Besides, resveratrol is freely available in red wine and not patentable as such.

Building a 16 ft. Grand Banks Dory

As a kid, I did a lot of boat building, mainly scale models that were not able to sail, although I did actually build a few boats that were, more or less, capable of sailing. I even once build a 10 feet boat, or shall I say raft. I accomplished this with a few friends and we had great fun sailing it on the local river. It was not really waterproof and while one person was rowing, the others had to make sure that they removed the water quicker then it was entering our boat.

Then sadly one day we failed. I was rowing at the time, and we were in the middle of the river when it was clear we were sinking. I stopped rowing to assist with the hosing, but this only slowed down the process of sinking, it did not stop it. So I started to row again in on the effort to reach dry land before we sank, thus avoiding having to swim to safety. 

And guess what: We made it! Just before the boat really started to sink we managed to jump ashore. Here we watched as our pride and joy slowly sank to the bottom of the river. It was then that we realized we were on the wrong side of the river and this left us with a problem. We either had to walk to the nearest bridge, 10 kilometers upriver, so that would have been a 20-kilometer walk, or swim to the other side.

We decided on swimming. We did not see anyone around, so we quickly undressed, and with one hand holding our clothes above the water, we managed to get back to our own side of the river. Just as we were struggling to get out of the water a group of girls from our own school was passing by, and I can tell you we were not happy!

This all happened a long time ago and a few times in my life I have had plans of building a boat again. I have spent a good amount of time looking at boat building plans, but with boats, size does matter. 



I usually looked at boats between 30 and 40 feet, but the sheer volume of work involved has always stopped me from going ahead with my boat building plans. 

Now I have decided to start small. I am going to build a 16 feet Grand Banks dory, which I want to fit with a small outboard engine. I bought the boat building plans, I got the working space, and by the time you read this article, I might be finished already. 

Later, who knows, I might build a 40 feet cabin cruiser, and tow my Grand Banks dory behind me. Then, if my cabin cruises sink, I can always row to safety in my Grand Banks dory, dry and with my clothes on.

Radio Sports For Die-Hard Hobbyists

Contest-Station - Photo: Wikipedia
Radiosport as a term is sometimes used as two separate words, or as a single word. It refers to the use of amateur radio equipment or the “ham”, in short, as a part of playing some sort of game. It might be a group event or a single person event. It can involve other competitors in real time like a race or like a performance or achievement over a given time frame.

The contests are usually sponsored events and can last anywhere between a few hours and 2 days, the worldwide contests being two days usually. It can be local in a specific region or may involve traveling a long distance.  It can be a cumulative contest taking place over many weekends, or a sprint contest which lasts only a few hours. The rules are specific for the event and they include which stations (which regions) may participate and the like.

This is usually called radiosports. This can be any of the following.

Dx-Contest:
This is when stations are to make two-way contact with as many stations as possible over the longest distance possible. This is called the International DX-Contest today. Awards may be given for the following accomplishments. The “Worked All States Award” if the entrants make contact with someone from every state in the USA. The “Worked All continents Award” is given for making contact with someone from every continent. “Worked All Zones Award” is the same concept with time zones. Other awards include the DX Century Club award and the UHF/VHF Century Club award.

Another event is an Amateur Radio Direction finding using radios. A specific number of transmitters needs to be found from a specific region on a map before reaching the end line. This relies on the athletic ability of the ham operator as well as some direction finding skill with radios.

Fox Oaring or Bunny hunting: This is similar to the previous contest but involves more short-range equipment of the hams, and so it relies more on the direction finding skills of the contestant rather than the athletic ability. It’s more technical in nature than the previous contest, and the radio can detect signals only 100 meters or so away, so the contestant must locate the transmitter hidden in an area of a 200-meter radius.

A more severely restricted game than the Fox Oaring is the Radio orienting contest in compact areas. This requires very high technical skills.

There is another form of the amateur radio direction finding, or bunny hunting, that utilizes transportation with vehicles over long distances. The hams have to travel in their vehicles to the specific region and find the transmitter. Whoever finds the transmitter first and reaches the finish line is the winner. A variation is that the one to find a specific number of transmitters hidden in different places first is the winner. This relies on the traveling skill, orientation skill and the equipment efficiency too.

These events are called ARDF contests, which is short for Amateur Radio Direction Finding Contests. Contests or radiosports are just a part of the hobby activity. Entering contests is not a requirement, but there are many who pursue this almost obsessively and collect winning certificates by the dozen in fact. On the other extreme are those that are equally passionate about being a ham, but do so purely for communication and satisfaction.



The significant thing about hams that need to be mentioned here is that the hams can and do make regular contact with space stations. Many astronauts are licensed amateur radio operators and use their radios for educational purpose as well as an emergency backup.

So what was once spanning a small region locally in the beginning now has penetrated into space! What was once only Morse code based has now evolved into greater variations involving voice, digital transmission and so on? It is exciting to see how much radio transmission has changed in recent years.

RADIO ASTRONOMY

For most of us, the idea of astronomy is something we directly connect to “stargazing”, telescopes and seeing magnificent displays in the heavens.  And to be sure, that is the exciting area of astronomy that accounts for its huge popularity.  So to the uninitiated, the idea of “radio astronomy” seems strange.  There are two reasons for that.  First is that humans are far more visual than audio oriented.  And the second is that radio astronomy doesn’t really involve “listening” to the cosmos except to the extent that scientists who use this sophisticated form of “stargazing” do not rely on the visual study to conduct their work.

To appreciate what is really exciting about radio astronomy, first, we have to shift how we view astronomy.  That is because to professional astronomers, studying the universe is more about frequencies than it is about visual documentation of phenomenon.  This takes us back to Physics 101.

Light, obviously, is the physical phenomenon that empowers our ability to use our visual confirmation system, e.g. our eyes to appreciate something, in this case, the stars.  So when we look up at the heavens, we can see the light emitting from a star or reflecting from a planet or moon.  In many cases, if we see a faraway star, we are actually seeing it hundreds or thousands of years ago because that is how long it takes for that light to cross the universe and be visible in our sky.  That alone is a pretty mind-blowing idea.

Now light itself is a pretty strange substance.  But to our astronomy scientists, light is just another energy that exists in a certain frequency.  Now, we tend to think of frequencies when we talk about sound waves.  In scientific terms light, energy and sound are just a few forms of the same thing, frequencies of energy that are emulating from a source.

Now we get to why radio astronomy is so necessary.  The range of frequency that light occupies in the big spectrum of frequencies is really pretty small.  To put that more bluntly, we can only “see” a tiny part of the universe that is actually there.  Now when you look up in the night sky and it is so overwhelming, when you then that we are seeing just a tiny amount of what is actually going on up there, again, our minds can get pretty overwhelmed.

Radio astronomy uses sophisticated sensor equipment to study ALL of the frequencies of energy coming to us from the cosmos.  In that way, these scientists can “see” everything that is going on out there and so get a precise idea of how the stars look, behave now and will behave in the future.

For some of us who have heard about radio astronomy, we think of it in terms of “listening” for signs of life in the universe.  And yes, SETI, or “the Search for Extra-Terrestrial Intelligence” is a part of radio astronomy, albeit a tiny part.  But of much greater importance is how radio astronomy has empowered serious astronomers (that is those who get paid to do it) to study stars many light years away, to study black holes which we could never see with our telescopes and to gather research and data about the whole of the universe that otherwise would be impossible to know and understand.



This is important work that is constantly ongoing in the world of astronomy.  It is worth keeping up with and learning more about as we have barely scratched the surface in our brief discussion today.

But understanding how important radio astronomy is will only deepen and make more meaningful your love and grasp of this big field of knowledge known as astronomy.
